My bad. Forgot to remove the localversion-tip file.

Can you try to enable the following config options:
CONFIG_DEBUG_OBJECTS
CONFIG_DEBUG_OBJECTS_FREE
CONFIG_DEBUG_OBJECTS_TIMERS
CONFIG_DEBUG_OBJECTS_ENABLE_DEFAULT

Don't bother. Just noticed that this is nf_conntrack context. Working
on that right now.

I'm running rc6-rt3 and that problem seem to be gone (uptime of 2.5
hours in my desktop, 1.33 hours on my laptop, both running FC9 with a
2.6.29 version of the Planet CCRMA rt kernel). So far so good!
Thanks!!

One of my Planet CCRMA users tried the rc6-rt3 kernel and...
Traceys says:

This is similar to what was happening to me with rc6-rt2, maybe another
driver with a similar problem?

[-- Attachment #1: Type: text/plain, Size: 434 bytes --]
After a quick test some BUG's on boot (on a quad core intel machine),
I'm just attaching the whole dmesg output as that might provide more
clues...
In short, two types, one BUG and another WARNING:
BUG: sleeping function called from invalid context at
kernel/rtmutex.c:683
WARNING: at fs/sysfs/group.c:138 sysfs_remove_group+0x3e/0xa8()
Thanks again for all the hard work!
(and looking forward to the next rt patch!)

More testing and an Oops that prevents booting... maybe unrelated to rt?
(this is with 2.6.29-rc8 plus additional patches from Fedora's koji
build 61 for fc10). First time my laptop does not boot with the new
kernels on a long time.
See below.

perhaps try excluding the microcode module for now - maybe it messed

does any of the Fedora patches you have applied involve wireless
changes? I'd suggest undoing those first.

Strangely enough rc8-rt1 boots (almost). _Exact_ same build with the
exception of the change from rt1 -> rt2.
Haldaemon does not start on boot (fails), if I login as root and start
the haldaemon service manually it starts. And then things seem to work
fine (I'm writing this email from that machine). Still investigating...

First problem was due to old firmware for the iwl3945 hardware. I
updated to the latest and hal started fine (this is on fc9).
Now another one related to xorg/drm...
Oh well...

Scratch that, I had an old version of xorg/drm installed in this
particular machine and the new kernel did not like it. Seems to boot
fine now... sorry for the noise.

No problem :-)
I'm wondering, do you have any theory about how the old firmware
cause that weird NX-fault kernel crash? For a few minutes i took it
for an x86 crash.

Sorry, no theories at all - I would have to be a kernel guru for that. I
was surprised the whole thing went away with the firmware upgrade (I saw
some message in /var/log/messages telling me the firmware was old) - it
did seem like something more serious.
I hit another problem. On a quad code intel machine here at home there
is a problem during shutdown. The final shutdown dies with a traceback
(something like "rc0 was killed by SIGSEGV" or similar words at the very
end). Then I have to push the power button for x+ seconds to force a
power off.
Should I post a picture of the screen as it is at that point, or just
send that to you and Thomas?

any kernel stack dump in that?
You could try to do this before shutting down:
echo 1 > /proc/sys/kernel/print-fatal-signals
dmesg -n 8
that way there's a (hopefully helpful) stack dump done of the
SIGSEGV itself.

Hmm. Do you have CONFIG_HAVE_DYNAMIC_FTRACE=y in your config ? If yes,
can you please disable it ?

The crash happens in alternatives_smp_switch(). Can you check whether
adding "noreplace-smp" to the kernel command line helps ? I boot your
config on my own T61. Hopefully I can reproduce.

Booting with noreplace-smp fixes the problem in my case, I can shutdown
with no problems.

The problem is still there in 2.6.29-rt1...
Booting it I got this, but not all the time (I'm writing from the T61
having booted successfully...):

Doing this in arch/arm/include/asm/bitops.h is less intrusive and it
seems to me the better place. See my patch stack.

It would be easier to check your patch if it didn't contain reverts of
earlier changes.

Hi
It is great to see that the -rt patchset is moving again.
> http://www.kernel.org/pub/linux/kernel/projects/rt/patch-2.6.29-rc7-rt1.bz2
This should be
http://www.kernel.org/pub/linux/kernel/projects/rt/patch-2.6.29-rc7-rt1.patch.bz2
As far as i understand this is again for x86. I tried some patches to get the
ARM platform working as the platform i am working on (phytec i.mx31) is not
supported by the stable 2.6.26-rt release. The attached patches are for
reference only as i think some of them are on their way via the pengutronix
git tree and others are just hacks to get this thing compile. These patches
enable rt functionality as tested with cyclictest but the kernel is not
stable, so some pieces are missing.
So my question is, what pieces are missing on the ARM platform to get it working?
Regards
Tim
The following patches are against the 2.6.29-rc4-rt2 in an attempt to get ARM working.

- fix CONFIG_HIGHMEM problems
- fix netfilter problems
- make debugobjects -rt safe
- various build fixes
