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@kernel-bugs.osdl.org
ReportedBy: Martin@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.

The title is inaccurate. This is actually a null-pointer deref in
ttm_bo_reserve().

Looks like you ran out of graphics memory. What size is your AGP aperture set
to? Please attach your dmesg output.

dmesg of 2.6.37-rc3
Andrew, thanks for hint regarding the title. I changed it as per your
suggestion.
Alex, dmesg of freshly booted 2.6.37-rc3 (upto KDE Display Manager). Tell me if
you need 2.6.36 as well.

syslog with more backtraces
this syslog contains some additional backtraces. Including another occurence of
this with 2.6.36 where kwin got stuck in a 95-100% CPU loop and the desktop was
basically frozen, no mouse movement, no switching to tty. And some allocation
features with previously booted 2.6.37-rc3 after playing around with desktop
cube and effects which feel a bit faster than with 2.6.36.
I will test the two desktop gfx corruption case tomorrow during holding my
training.

You can try increasing your AGP aperture size in the bios, but there's not a
lot you can do if you run out of graphics memory other than trying to handle
things more gracefully.

I did not found any option for this in the ThinkPad BIOS. But shouldn't the
driver just get more slow, i.e. increase swapping of textures between gfx card
and main memory, when gfx memory is low? Well, maybe thats what you mean by
"more gracefully". Anyway, will run without compositing when using two sessions
simultaneously. Seems fair enough with that old gfx card ;). Will leave this
report open as reminder for the "more gracefully" thing, i.e. to fix that null
pointer deference for example ;). Thanks.
