I'm getting a kernel panic when I exit xorg-server. I have * ATI Mobility X600 * KDE4.2.1 * xorg-server-1.5.3-r5 * xf86-video-ati-6.12.1 * x11-drm-20090320 On exit X11 I get something like vblank_disable_fn vblank_disable_fn run_timer_softirq __do_softirq ... On Kernels >=2.6.28-gentoo-r3 (-r2 and lower work!). What can I do? Reproducible: Always Steps to Reproduce: Actual Results: Kernel Panic - Have to hard reset the machine. Expected Results: Should not crash.

Ok try to use in-kernel drm or use live drm.
Thank you for the tip. I removed x11-drm-20090320 und enabled CONFIG_DRM_RADEON in the kernel. Nope. Same situation. :( Quite when terminating X11, I can see the Console with my PS1 prompt. But soon after I get something like this: --->snip---> Oops! 000 ... EIP is at radeon_get_vblank_counter+0x76/0x8c [radeon] ... Call Stack: vblank_disable_fn+0x82/0xd6 [drm] vblank_disable_fn+0x0/0xd6 [drm] run_timer_softirq+0x156/0xdd __do_softirq+0x2a/0x2f irq_exit+0x59/0x6c do_IRQ+0x59/0x6c ... Not syncing ... <---snap<--- Maybe I didn't get the right values and wording. I don't have an electronic copy of this ourtput ... is there some chance to get one? Things started to be broken with 2.6.28-gentoo-r3. This is currently 2.6.29-gentoo with CONFIG_DRM_RADEON. Oh - BTW - this is as well with these installations: $ eix -ce xf86-video-ati [I] x11-drivers/xf86-video-ati (6.12.1-r1@04/02/2009): ATI video driver $ eix -ce xorg-server [I] x11-base/xorg-server (1.5.3-r5@04/02/2009): X.Org X servers What's the live drm you noted? Can you point to any resource? Thanks for help.
Hm interesting is that it fails with in-kernel module :( The live drm is in x11 overlay :] layman -a x11 or how is layman used these days :]
Remove me from cc, i am in X11 alias cc too (i hate getting 2 mails for one thing :])
having same problem for some time. different-version of xf86-video-ati (but 6.8.0 works) and x11-drm libdrm... No, live drm still doesn't work. if i exit X and remove radeon-module (rmmod radeon) before reboot/shutdown kernel doesn't crash. noticed since these crashes, xvinfo shows 2 adapters. I have a radeon 9700 mobility. on a PC with a hd3300 this prob doesn't occur.
Same here also with x11-drivers/xf86-video-ati-6.12.1-r1. I've even played a bit with keywording of different packages (xf86-video-ati, x11-drm, libdrm ...) and I haven't found yet (again) which combination works. I'll post more info later.
hello. i have exactly the same problem using ati drivers 6.11 or 6.12.* and (vanilla) kernel 2.6.9
Confirmed for another system. With xf86-video-ati-6.12.1-r1 kernel panics for 2.6.29-r1, 2.6.28-r5, 2.6.26-r3. Does not panic with xf86-video-ati-6.8.0-r1. Was stable previously with 2.6.26-r3 and older xf86-video-ati. Video: ATI Technologies Inc RS300M AGP [Radeon Mobility 9100IGP] Host bridge: ATI Technologies Inc RS300 Host Bridge (rev 02) PCI bridge: ATI Technologies Inc Radeon 9100 IGP AGP Bridge Other software: x11-base/xorg-server-1.5.3-r5 x11-base/x11-drm-20090320 Did not try changing x11-drm based on previous comments in this bug.
Switched to Kernel 2.6.29-gentoo-r2 ... still panic. No change. Bump.
Can someone post a photo of the oops please? There is some important information missing from the details posted to this bug up to this point. thanks!

Thanks. This bug has an analysis: http://bugs.freedesktop.org/show_bug.cgi?id=20954 There's a patch there that you could try applying to drivers/gpu/drm/radeon/radeon_irq.c in the kernel source.
Because I didn't know how to apply this patch to x11-base/x11-drm-99999999, I switched to the modules in the kernel and patched it. works!
Created attachment 190996 [details] Patch for x11-drm-20090320 radeon kernel panic Patch for x11-drm-20090320 radeon kernel panic. Place it in /usr/portage/x11-base/x11-drm/files/ (got to create the folder).
Created attachment 190998 [details] ebuild file containing radeon panic patch Ebuild file containing the http://bugs.freedesktop.org/show_bug.cgi?id=20954 patch
Created patch file and ebuild for x11-drm-20090320. Could plz someone verify? I can compile and merge, but I'm currently unable to verify if this solves the panic ...
works too
Thanks. I'm not convinced the fix is correct or will be accepted though. Could someone please revert that patch and any other changes, return to a "broken" system. Then run as root: dmesg -n 7 echo 1 > /sys/module/drm/parameters/debug halt and take a photo of the new crash-on-shutdown Please be using a framebuffer like jamatik in comment #13 so that the top of the crash can be seen. thanks!

Did you definitely run the dmesg and echo commands to enable debug? I would have expected more messages to appear on the console above. Maybe they did and they just aren't visible in the photo?
Yes, I did. and that's the result.

That's different, since I - and I assume everybody else in this bug request - is using the FOSS drivers. Is this realy the same incident?
@Oliver Maurhart Yes I am using xf86-video-ati-6.12.2 I had been using the fglrx driver prior but the open source driver's 3D performance is good enough for molecular graphics. I switched since fglrx has refresh issues and hard lockups running opengl programs. lspci lists all of the kernel modules not just those loaded. Update -- I didn't read the warning messages carefully enough and am recompiling the modules since they won't load into the kernel with mmio_trace enabled.
Rebuilt radeon and drm modules with MMIOTRACE=y in linux-2.6.28-gentoo-r5. Symptoms are same as before when exiting xorg-server. However, enabling mmio_trace (by running "echo mmiotrace > /debug/tracing/current_tracer") before running startx causes a hard lockup at Gnome loading screen. The kernel log has many lines with DRM debugging output and finishes with 10 lines like those posted in comment #25 (drm:radeon_* and drm:drm_* lines). I have saved the mmio_trace output as well as kernel log with debug for drm module enabled. Please let me know if any of the files would be useful since the output is verbose and I am unsure whether the kernel log and/or mmio trace would be useful.
I'm not sure how mmiotrace could help us here but I don't know much about it. Re comment #25: thanks, but usually when the kernel crashes it is not able to save much information to disk (as illustrated by the oops not being in your logs). We need to see the debug messages that appear immediately above the oops, so we really need a photo or hand-transcription of the oops *including* the few lines above (which are very unlikely to be in the logs)
fixed in kernel 2.6.30 using gentoo-sources-2.6.30-r1 + in-kernel drm (+ xf86-video-ati-9999)
can anyone else confirm that 2.6.30 solves the problem?
Ok. I'll try once I'm back home (rd. 3-4 days from today). My machine is currently blocked ... by work. :(
Recompiled my kernel yesterday in the hotel applying in-kernel CONFIG_DRM and CONFIG_DRM_ATI together with xf86-video-ati-6.12.2 on a gentoo-sources-2.6.30-r1 (x32) ... it works! No kernel panic on exiting X11 so far (tested 4 times now). Composite effects in KDE 4.2.4 back. So ... am I to close the bug now, since I opened it up? Well, I do. I treat it as fixed.
