Description nissarin 2011-09-01 15:35:49 UTC 
Basically, some time after login I experience GPU stall, after that the X environment becomes unusable due to more errors ("couldn't schedule IB"),so I've to switch to console to reboot the PC.

If I'm not mistaken, I hit this as soon as I tried 3.1 (rc2, perhaps even rc1 ?) but at this point I'm not sure about this. 
Kernel 3.0 (+some stuff from airlied - radeon-testing/fixes) works fine. 

I've no idea how to reproduce this - usually I'm running only Firefox and/or Thunderbird and some terminal windows (ssh sessions, rtorrent). It can happen a few minutes after login or after a few hours, the one below actually took some time as normally it's within a hour. 

I'm using...
 - Radeon 6850
 - Gentoo/AMD64 system
 - Xfce/xfwm v4.8.1 w/ compositor enabled
 - xorg-server 1.10.4/1.11
 - ati-driver (r600g), libdrm and mesa from git

I could try to bisect this but due to nature of the bug I don't know how long it would take.

Comment 1 Niels Ole Salscheider 2011-09-01 15:45:56 UTC 
This might be the same as bug 42162, which I bisected. You could try if commit b03e7495a862b028294f59fc87286d6d78ee7fa1 is the first bad commit...
Comment 2 nissarin 2011-09-01 16:42:41 UTC 
OK, after some "extensive" testing (as in glxgears x 20, duh) b03e7495a862b028294f59fc87286d6d78ee7fa1 "crashed" near 30 minute mark. Currently I'm running 5f66d2b58ca879e70740c82422354144845d6dd3, lets see what happens.

As a side note, I've noticed you are also using Gigabyte mobo...
I might be oversensitive here but I encountered some strange bugs before, bugs which can be annoying yet I didn't saw many ppl reporting it.
Comment 3 nissarin 2011-09-02 00:59:20 UTC 
More than 8 hours have passed without a single glitch (same as before.. glxgears, web browser, wesnoth, etc.) so yeah, it appears that b03e7495a862b028294f59fc87286d6d78ee7fa1 is most likely the cause.
Comment 4 Alex Deucher 2011-09-02 05:02:08 UTC 
Should mark this as a dupe of bug 42162 then.  Does the patch on bug 42162 help?
Comment 5 nissarin 2011-09-02 09:52:26 UTC 
Yes, it seems to be the same issue. Currently I'm testing the patch, I'll notify you later if it worked for me.
Comment 6 nissarin 2011-09-03 01:18:38 UTC 
The patch works, thanks.
