Changeset in question is a memory corruptor fixed almost immediately
afterwards.  So if that's where bisect _ends_, I'm afraid that this
is not the end of story.

Still present both in Linus tree and sched-devel - root cause is not
yet well understood per Ingo.

Worked around by disabling GROUP_SCHED stuff by default (commit
aac6abca858386438d9a7233c3471d2ecfa2f704 ).

What causes this regression?

Is this commit 018d6db4cb5bbdcd65424a16f2dcca692ed32ae4
(sched: re-do "sched: fix fair sleepers") that had already been reverted 
in 2.6.25 for causing such regressions or is this caused by a different 
commit?

Both current -git and sched-devel have this problem - that means it's
unrelated to the commit you refer to unless it was reintroduced in a
different form but same effect.

It is related to:

1. Debian gcc in stable being used to compile the kernel
2. unmodified led_set_status() function on thinkpad-acpi.c
3. kernel compiled in "optimize for size" mode
4. stack frames NOT being enabled.

Change one, and the bug is gone.

AFAIK, it means Debian stable's gcc is generating bad code.

But I need help from someone with good knowledge of gcc to give us the
final word on it.  I might be doing something stupid in thinkpad-acpi.c,
after all.

I will attach the relevant data to the bug report.

that should be resolved via your patch which i pushed upstream (commit 
v2.6.26-rc1-83-gaac6abc), which marks group scheduling experimental and 
non-default.

i think the audio skipping from Miklos, if it does not go away with 
disabling group scheduling, might also be solved by:

 - commit v2.6.26-rc1-181-g4615112 ("sched: fix weight calculations") 
   from Mike.

 - or by commit v2.6.26-rc1-82-g3e51f33 from Peter ("sched: add optional 
   support for CONFIG_HAVE_UNSTABLE_SCHED_CLOCK") which makes the 
   scheduler clock more reliable [and hence produce no artificial 
   latencies] on NOHZ

 - or by commit v2.6.26-rc1-66-ga992241 from Peter ("sched: fix 
   normalized sleeper").

Yep, disabling group sched fixed it.

It's no regression but just a problem of a new driver.  The reporter
must have added the new config (CONFIG_SND_PCSP=[y,m]) explicitly.

No, it's not that commit. That commit also caused a (less severe and fairly 
hard to reproduce) latency issue, but that has now been fixed by the patch 
listed in the BR (committed as a992241de614dd2b7c97a9ba64e28c0e563f19bf).


The issue reported by Parag as "Horrendous Audio Stutter" (and confirmed by 
me) is much more severe and is indeed related to group scheduling.

The group scheduling related issue disappeared for me with -rc1 after 
reverting the following two commits (as suggested by Mike Galbraith):
- 7ba2e74ab5a0518bc953042952dd165724bc70c9
  sched: debug: show a weight tree
- 8f1bc385cfbab474db6c27b5af1e439614f3025c
  sched: fair: weight calculations

Given the confusing and partially incorrect information in this BR, it seems 
best to me to close it and open a new one for the issue reported by Parag.

Patches were merged upstream yesterday and this specific compile error 
does not happen any more.

However, there are 2 page-related link errors, now that it got to 
linking stage:
ERROR: "copy_page" [fs/fuse/fuse.ko] undefined!
ERROR: "empty_zero_page" [fs/ext4/ext4dev.ko] undefined!

Should I report these as different errors or is is related enough?

People who include this driver (either because they added it thinking
it wouldn't do much), or because their distro compiles lots of stuff
as module, could potentially get surprised, if it renumbers how the
soundcards are enumerated.  On my system, my sound card ended up going
from hw:0 to hw:1, which given my ~/.asoundrc, meant that sound
appeared to be broken with errors such as this:

aplay: set_params:900: Sample format non available

Once I edited by ~/.asoundrc file to use hw:1 instead of hw:0 the
problem went away, so it's really not a kernel _bug_ per se, but the
result might be surprising.  Maybe there should be a quick warning in
the Kconfig file?  It's not that big of a deal, but I did end up
spending quite a bit of time trying to track down what I initially
thought was a regression.

No, your code is buggy:

                rc = led_set_status(led, s);

According to the assembler code "led" is in register EBX, and in the 
trace the value of EBX is 0x80.

0x80 = 1 << 7

What happens when you write to tpacpi_led_state_cache[0x80] is 
undefined, and it's not a surprise that random changes let the
bug seem to disappear.

Sounds reasonable.  To where should it be added, BTW?
Little people seem to care about Kconfig help texts, and an extra
comment block (with depends on SND_PCSP) could be annoying...

That's a good question.  A note that including including this module
could potentially cause sound cards to be renumbered might be
reasonable, since I suspect most users (and most application
programs!) have been accustomed to only having one sound card, and so
building this module may cause sound cards to be renumbered in Kconfig
would at least be a start.

I know this wouldn't help users of distro kernels, but this would at
least be one way of warning distro maintainers to think twice about
enabling it as a module.  BTW, what *is* the utility of this card, and
how do you use it?  I haven't been able to figure out how to use it do
anything entertaining at all.  Any attempts to use it on my system
just lead to various confusing error messages.

Also, BTW, it might be nice to remove the following hunk of text from
drivers/sound/Kconfig:

	I'm told that even without a sound card, you can make your computer
	say more than an occasional beep, by programming the PC speaker.
	Kernel patches and supporting utilities to do that are in the pcsp
	package, available at <ftp://ftp.infradead.org/pub/pcsp/>.

What's there at the above URL is for the 2.2 and 2.4 kernels, and the
utilities at pcsnd-kit.tar.gz don't work (and didn't compile until I
futzed with them slightly).

So I'm still rather puzzled how to make the snd-pcsp actually do
anything useful, unless it simply doesn't work on my Thinkpad.  (Is it
normal that the sound volume levels reported by alsamixer can be muted
or unmounted, but always report 0, and can't be adjusted up?)

Yes.

Well, yeah, for distro kernels, it's then a problem of distributors :)

It looks like a problem in the recent alsa-lib.  This driver works
fine without dmix, e.g. "aplay -Dplughw:1 foo.wav" works.
I'll investigate later.

OK, I'll clean it up, too.

It can be adjusted via alsa-lib softvol plugin.  That is, the volume
attenuation is done in the user-space, not in the driver.

I guess so, and in the description

to the effect of "READ HELP!".

Any utility will do.

That's because it is a bit broken
in alsa-lib right now, more details
and the fix here:
http://lkml.org/lkml/2008/5/11/172

Yeah - that old driver never worked
with alsa anyway, so that removal is
an overdue. :)

It will be handled properly by default
with the next alsa-lib release. But the
trivial fix on the above URL should work
too.

It is actually a problem in a non-recent
alsa-lib. With alsa-lib from hg it works
fine, but breaks with 1.0.16.
The commit that introduced an incompatibility
is this one:
http://hg-mirror.alsa-project.org/alsa-kernel/diff/26b0243ab4fa/drivers/pcsp/pcsp_lib.c
I certainly was not considering the
maintenance problems it creates. :(
Perhaps should we revert this commit
for now, and reintroduce after the
next alsa-lib release?

FYI, the alsa-lib fix is this one:
http://hg-mirror.alsa-project.org/alsa-lib/diff/8a980469cd71/src/conf/cards/PC-Speaker.conf

The problem happened because the
softvol plugin doesn't support 8bit
formats. So the above config change
was needed.

I don't know if this would be considered too ugly a suggestion to put
in the Kconfig description, but the suggestion in:

http://lkml.org/lkml/2008/5/11/172

To put the following in /etc/modprobe.conf:

options snd-pcsp index=2

Would probably avoid confusion for most users.  It's more than a
little bit hackish, and I imagine I can imagine hotplug/udev fanatics
throwing up all over their keyboard, but short of having udev rules
that run around editing user's ~/.asoundrc files, or creating some
kind of system wide naming scheme so that people can use stable names
in their alsa config files, this is going to be an, ah, "interesting"
problem for various sound applications to deal with.

In any case, here's what I mean, in
an attached patch.

PS: please let us know whether the new
PC-Speaker.conf allowed you to get any

I tried replacing it, but I'm still getting silence when I use "aplay
-D plughw:0,0 /usr/share/sounds/login.wav".  If I use "aplay -D
hw:0,0", I still get the "aplay: set_params:900: Sample format non
available" error message.  This is with Ubuntu Gutsy; for a variety of
reasons, I haven't yet updated my primary laptop to Hardy yet.  I can
try booting a bleeding edge kernel on my Hardy machine and see whether
it works any better there.

You don't need to specify anything
with the fixed conf. You probably
even _should_ not. Could you please
just try "aplay /usr/share/sounds/login.wav"
or mpg123 or anything else the most
usual way you do?
Oh, and it would be best to remove
for the moment the custom /etc/asound.conf
if any.

Well, yeah, it would be nice to have
alsa-lib 1.0.16, which one is on Gutsy?
The older ones may not support that
driver even with the good config.

PS: your messages are a bit strange.
When I press "Reply to All" in a
thunderbird mailer, it sets all the
e-mail addresses as "To:". And it
includes my own address. And it includes
your address twice. This is weird. I
am fixing that by hands.
With all other messages, by pressing
"reply to all", it composes the message
with all addresses set to "Cc:", and only
one is set to "To:", with my own address
not included at all

OK, with my ~/.asoundrc file moved out of the way (but with the fixed
config file installed):

# aplay /usr/share/sounds/login.wav 
ALSA lib pcm_direct.c:901:(snd_pcm_direct_initialize_slave) requested or auto-format is not available
ALSA lib pcm_dmix.c:876:(snd_pcm_dmix_open) unable to initialize slave

# aplay -D hw:0,0 /usr/share/sounds/login.wav 
Playing WAVE '/usr/share/sounds/login.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
aplay: set_params:900: Sample format non available

# aplay -D plughw:0 /usr/share/sounds/login.wav 
Playing WAVE '/usr/share/sounds/login.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
  <no sound, but aplay sits there as if it was sending sound to a muted
  speaker and exits after approximately the amount of time for the wav
  file would take to play>

Is moving ~/.asoundrc out of the way sufficient?  Or do I need to
reboot or logout/login again to clear something?  I don't think there
are any user space daemons involved here, but...

Hmm, I don't know.  I'm not setting a reply-to header.  My e-mail
messages do have an SMTP envelope from field of tytso@thunk.org, but
that shouldn't be visible to MUA's.  (It just means that MTA's send
bounce messages to tytso@thunk.org, which I need to do since my
outgoing e-mail path goes through thunk.org, and if I didn't do I
might trip certain spam filters which check to see if the domain of
the SMTP "MAIL FROM" matches the domain of the sending SMTP server.)

In any case, my outgoing RFC 822 message headers on my end looks like
this:

Thanks. Probably .26 material; many people will likely just disable the 
driver upon not seeing it work (and not re-enable it later also, meaning 
it might be a very largely unused driver) otherwise.

More seriously, it doesn't seem that there's any way we can build
this driver modular without it screwing up already working systems
unless we cripple its MODULE_ALIAS to not autoload, allowing users
who care about it (which will be in the minority anyway) to add it manually.

Maybe it is possible to adjust the
/etc/modprobe.d/modprobe.conf.dist
of module-init-tools and add there
something like the following?
options snd-pcsp index=10
It will then never became a default
driver.

Unless someone has 10 sound cards :-)  (Sounds bizarre, but I never tire
of seeing some of the creative situations our users get themselves into).

Something like this is probably the only real supportable way to do it though.
It would be great if alsa took something like -1 to mean 'never make this default'.

But until that lands in a module-init-tools update, we're kind of stuck.

Yes, the hardcoded values sucks...

> It would be great if alsa took something like -1 to mean 'never make this default'.
-1 seems to be already reserved for
"use first free slot", but maybe it
would be nice to reserve some value
for the "movable" index. For example,
the index -2 can mean "use the first
free slot, but move to the next one
when some other driver is registering
with -1 or explicitly to that slot".
Of course I have no idea whether this
is possible and acceptable, but maybe
the alsa guys can tell.

> But until that lands in a module-init-tools update, we're kind of stuck.
Well, they won't take 10 or any other
value I guess...

Actually, I have just upgraded
f8->f9, and guess what? Lost the
sound... And not because of snd-pcsp,
but rather because snd-hda-intel
started to take the first slot
and snd-intel8x0 takes the second.
On f8 snd-hda-intel have never been
loaded for me at all. I don't need
it, it finds a HDA chip on an ATI
video board, which it never did before.

So... it doesn't look like this
problem is specific to snd-pcsp.
Anyone can get into that trouble
it seems.

You can better use slots option for snd module instead of specifying
index in each driver for 2.6.25 or later kernels.  That is,

	options snd slots=snd-intel8x0,snd-hda-intel

will assign the specified drivers in the first two slots.  And this
means also that these two slots are reserved.  The other drivers,
e.g. a hotplugged usb-audio, won't be assigned in these slots even
usb-audio is loaded before intel8x0.

See ALSA-Configuration.txt for details.
