Summary: probably radeon kms / memory shortage related
scheduling while atomic
Product: Drivers
Version: 2.5
Kernel Version: 2.6.36-tp42-gtt-vram-apart-v2-dirty
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Video(DRI - non Intel)
AssignedTo: drivers_video-dri at kernel-bugs.osdl.org
ReportedBy: Martin at Lichtvoll.de
Regression: Yes
Yesterday on using a translation plasmoid on KDE 4.5.3/4.5.1 I got a backtrace
loop with scheduling while atomic on my ThinkPad T42 with Radeon KMS. Since I
hadn't another machine up to SSH into my laptop and I was not able to get into
a tty, I rebooted it. But I think the kernel was still running. Harddisk LED
were active from time to time.

Goes on like this. TTM memory allocation errors like in the beginning of above
except I had at 9:42 and in the afternoon already, without noticing them.
Probably related is
Bug 31859 - graphics corruption on display :0 when using two sessions
https://bugs.freedesktop.org/show_bug.cgi?id=31859
but I only used one KDE 4.5 session at that time. I even restarted it to get
rid of those graphics corruptions.
I am using Radeon KMS on ThinkPad T42 with:
