Rather unspecific bug title, cause I do not know exactly where to sort this.
This is with:
martin at shambhala:~> cat /proc/version
Linux version 2.6.36-tp42-gtt-vram-apart-v2-dirty (martin at shambhala) (gcc
version 4.4.5 (Debian 4.4.5-4) ) #1 PREEMPT Thu Oct 21 12:10:49 CEST 2010
I only seen it once so far. This is upstream kernel with a with patch from
Bug 28402 - random radeon/kms/drm related freezes with kernel 2.6.34
https://bugs.freedesktop.org/show_bug.cgi?id=28402#c82
While using one of two KDE sessions on my ThinkPad T42 suddenly the X.org
display was replaced by parts of a backtrace that I now dig out from the
syslog:

After this I found that the KDE plasma desktop of that session wouldn't respond
to any click any more while other KDE applications on the same desktop and the
other KDE session still work. On looking at ps aux | grep plasma-desktop I
found the process to be in D state. An strace -p on the PID didn't give
anything.
In order to try to get the KDE session back working again, I tried to killed
its only child ksysguard, but this left it in zombie state, and then I did a
killall -u on the username. On this I got:

On this hint that a reboot was needed I gracefully killed remaining user
processes also from the other KDE session and initiated a reboot. I couldn't
leave the machine in that state longer cause I am currently holding a Linux
Performance Tuning training and need that laptop for work ;).
Sometime prior to reboot I had lots of processes in D state. I'll add a
ps-aux.txt as attachment.
Some things that come to mind:
1) This laptop is using in-kernel-suspend and that quite some hibernation
cycles prior to the bug.
2) I have libcgroup / cgroup-bin 0.36.2-3 debian packages installed. Currently
with the default configuration except for also activating the memory
controller.
shambhala:~> grep CGROUP_MEM /boot/config-2.6.36-tp42-gtt-vram-apart-v2-dirty
CONFIG_CGROUP_MEM_RES_CTLR=y
CONFIG_CGROUP_MEM_RES_CTLR_SWAP=y
For demonstrating purposes I did a mkdir in the cgroup filesystem and added the
current shell as process to it to show the memory usage the memory controller
accounted to it. I did not set any limit.
I'll add the complete syslog and an archive with quite some stuff from /proc
that might turn out to be useful in the course of the day in training breaks.
syslog already has the reboot after the bug happened. The traces are before.
There is also from eSATA PCMCIA related trace before. I am using a eSATA PCMCIA
controller for my external harddisks.
