Hello,

I am sorry for responding to your e-mail late. Takashi Iwai identified
the cause of this problem and provided a patch. I tested the patch and
confirmed that it solves the problem. The patch was integrated into
mainline with the following commit:

=== 8< ===
commit 461c6c3a0a23a8fac1a4b636e93ff5dfe599a241
Author: Takashi Iwai <tiwai@suse.de>
Date:   Mon May 25 08:06:02 2009 +0200

    ALSA: hda - Add missing check of pin vref 50 and others in Realtek codecs
    
    Some Realtek codecs like ALC861 seem to support only VREF50 while the
    current driver assumes it's only VREF80.  Check other VREF bits to set
    the correct value.
    
    Signed-off-by: Takashi Iwai <tiwai@suse.de>
=== >8 ===

Regards,

M. Vefa Bicakci

But it should definitely be retitled -- the commit bisect pointed out
has little to do with the problem. And Handled-by should point to Ivo
since he was asking for debugging info and stuff.

Retitle to "rt2x00: slow wifi with correct basic rate bitmap" or
something like that, it's not a bug in mac80211.

I'm trying to get an ftrace profile that covers the point in question,
but it might take me a couple of days.

That URL points to a patch for a different problem.  The "Oops in
usb-serial with keyspan adapter" has been fixed by commit

Ingo's tree had a fix for this by increasing the lockdep chain size
IIRC. I think it's worth updating the BZ with current info, Jon?

No, it's now hanging 20 seconds much later, after returning to
userspace :( But the dmesg log still has a hang of ~20.5 seconds just
like before, between two kernel messages...

Hmm.  Can you try to comment out suspend_device_irqs() and resume_device_irqs()
in drivers/base/power/main.c and see what happens?

Well, I think this bug is supposed to have been fixed, but I'm not really sure.

That's why it's still listed.

The lockdep problem has been fixed, yes.

The system lockup...I'm not sure.  I can't reproduce it with lockdep
enabled, and I get no gripes.  I'm going back to a non-lockdep kernel
just to see if that's actually involved at all, or whether the problem
(which hit me several times) has somehow just evaporated.

Last I heard the reporter was going to attempt a bisect, that was a

I've been having trouble reliably bisecting; sometimes seemingly-bad
kernels work OK and other times thought-OK kernels fail even though I've
stopped Gnome and HAL.

At this point I'm suspecting intermittent hardware failure and am
getting set up to test on a similar machine.

Oddly, that does seem to help. I'm sure it can't be a solution though :)

Not really. ;-)

Still, something like the (untested) patch below can be.  Can you please give

FWIW, I'm no longer able to make this happen.  No idea what has
changed...  But it seems to be gone, and nobody else has complained, so
I guess it's a non-issue for 2.6.30.  It can probably be removed from
the list.

Thanks,

Seems to work, though I'm not sure yet whether it really helps, that
needs some more verification, will let you know tomorrow.

Hmm.  The patch shouldn't matter for this box, except for one thing:
check_irq_resend() on resume.  Interesting.

The other one is a _powerbook_ bug, very different machine (powerpc
mac). macbooks are just almost ordinary x86 gear :-)

I'll try to tackle the trackpad problem.

Yes, I realized they were different.

Perhaps the VIA-PMU interrupt shouldn't be disabled in
suspend_device_irqs()?

Possibly, but then we did use to have all interrupts disabled
at some stage before going to suspend_late anyway no ? So it shouldn't
make a big difference.

The VIA interrupt must not be HW masked in the PIC on some machines
because it's the wakeup source, so we may have to force re-enable it
since it can be lazy-disabled, but those aren't the machines with the
trackpad problem so I think I'll need to have a closer look at what's
going on and get my head around it.

Haven't had a chance yet, hopefully today or tomorrow.

Ben.

Yeah, well, turns out it didn't help anyway:

The problem doesn't always happen. But now that it happens here again,

has the dmesg, you can clearly see the delay:

I managed to get an entire function trace between

and

which I've uploaded to

(WARNING: uncompresses to 574MiB!)

I'm not sure why the timing in there doesn't show the delay, Steven was
taking a look at that.

paga_legacy remains broken in 2.6.30-rc8, and I still have to

Quite frankly, it looks like resume_device_irqs() itself causes the delay to happen.

The next step would be to put a couple of printk()s in there and see which part
of it triggers the delay.
