Description Matthias 2011-12-16 08:38:42 UTC 
Hi there,

I encountered the following error:
X: radeon_cs_gem.c:181: cs_gem_write_reloc: Assertion `boi->space_accounted' failed.

on my x86_64 archlinux box. verified with newest arch-xorg version with video-ati driver replaced by git version.

Reproduce (very simple):
start xinit session (default, the one without any fancy window manager, just a xterm in it).
In xterm I did "yaourt -S milkytracker" to show some coloured output.
When asking me if I want to see PKGBUILD, X crashes.

Attached gdb to X (without stripped symbols from radeon driver):

I have a M4A78LT-M-LE, BIOS 0507    02/23/2010 board
with CPU0: AMD Athlon(tm) II X2 235e Processor stepping 02.

Dont ask about the onboard video chip, here is what dmesg says:

I also installed XFCE4. With very light usage I encountered the same problem. I did not try to reproduce it there, but it might be possible with some steps...

Does nobody except me use this kind of graphics chip under linux?! All other bugs I found to that crash are not relevant, the only one relevant was closed as fixed in april 2011.

I managed to compile libdrm and the radeon driver with debug symbols (and with O0). Here is a new backtrace:

Also the reproduce does not work 100% the times. sometimes it crashes only when I do one action inside yaourt, so there needs to be some more output on xterm... but mostly it crashes without me doing anything except calling yaourt.
Comment 2 Alex Deucher 2011-12-16 09:02:48 UTC 
What version of the ddx (xf86-video-ati) are you using?  Please attach your xorg log and dmesg output.

attached dmesg and xorg log. 

version is git aacbd629b02cbee3f9e6a0ee452b4e3f21376bd3
(also reproduceable with extra/xf86-video-ati 6.14.3-1)

Also tried libdrm from git (latest). the latest backtrace is with both packages from git, as attached logs are.

Comment 8 Michel Dänzer 2011-12-20 10:41:27 UTC 
I've attached two patches, one of which should fix the root problem in libdrm_radeon, the other of which should avoid the problem in xf86-video-ati. Can you verify that either patch alone fixes / avoids the problem?
Comment 9 Matthias 2011-12-20 10:45:29 UTC 
Thank you very much.

Unfortunately I'm not at home until january, 9th. I will try both patches (combined and individual) and reply here at that time.

Maybe someone else is affected too and can try that earlier than me? 3 Weeks is a long time :)

Did you get a chance to test the patches?
Comment 11 Matthias 2012-02-03 09:20:56 UTC 
Hi,

I tested both patches alone and combined just today, sorry for that delay.

I used "old" ARCH packages as base. Patches applied without any problem and both alone fixed the occurence of the bug.

I did not encounter any other problems during my test session (worked about 2 hours with firefox/graphical terminal/milkytracker on the system - this would not have been possible for even one minute without the fix).

Thank you very much!
Comment 12 Matthias 2012-02-03 09:22:49 UTC 
ah sorry,
I used these versions of todays archlinux repository, if it matters:
libdrm-2.4.28
xf86-video-ati-6.14.3
Comment 13 Michel Dänzer 2012-02-08 06:07:10 UTC 
Fix pushed, thanks for testing.
Comment 14 aceman 2012-02-08 11:02:28 UTC 
This was whole X server crashing?
May it be related to bug 33038? But there only a single program was crashing alone.

No, that was a bug in r600c, which is now dead in favour of r600g.
