Summary: [RV515] Kernel .35 onwards, Random X freezes while scrolling Product: Drivers Version: 2.5 Kernel Version: .35 .36 .37 .38 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-dri@kernel-bugs.osdl.org ReportedBy: drkvi-a@yahoo.com Regression: Yes
Created an attachment (id=55352) --> (https://bugzilla.kernel.org/attachment.cgi?id=55352) gdb of X using Kernel 2.6.38-02063802
From kernel .35 onwards the system freezes at random.
This is mostly while scrolling scrolling pages while they load in Firefox(most common) or while scrolling in Nautilus/Gedit windows while they load.
Once it freezes I'm not able to do anything, only the mouse pointer alone moves but nothing else responds. It seems to happen when there is increased disk read/write.(but I'm not very sure of this) I'm using btrfs for my /home partition.
This regression starts in Kernel 2.6.35-1-generic #1-Ubuntu SMP Sat Jun 5 06:18:25 UTC 2010 i686 GNU/Linux
While, I dont have any problems with Kernel 2.6.34-5-generic #14-Ubuntu SMP Fri Jun 4 06:18:40 UTC 2010 i686 GNU/Linux or MainlineKernel 2.6.34-02063407-generic #201009140905 SMP Tue Sep 14 10:10:14 UTC 2010 i686 GNU/Linux, both work fine.
Problem is also present in Mainline Kernel 2.6.36-020636 , Ubuntu Kernel 2.6.37-12.26 , Mainline Kernel 2.6.37-020637rc8 , Ubuntu Kernel 2.6.38-1 and Mainline Kernel 2.6.38-02063802
I'm not able to test with kernel .39 because I'm having network issues with that.

Can you bisect?
I have never bisected a kernel, but I can try. Just have a few doubts.
1 * Can I do with the Ubuntu kernel as per Ubuntu instructions[0] as: $ git bisect start Ubuntu-2.6.35-1.1 Ubuntu-2.6.34-5.14
Which seems a saner incremental interval of Jun5 -> Jun 4.
Whereas Mainline Kernel 2.6.35-020635rc1-generic #020635rc1[1] which is dated Jun 1 had the problem , but Kernel 2.6.34-02063407-generic #201009140905[2] dated Sep 14(!!!) did not have the problem.
2 * Are there any pointers to narrow down the kernel commit from the backtraces I have posted? Or is just looking for "drivers/gpu/drm/radeon/" the closest?
3 * Is there any specific command I need to run if I hit the bug? Or is gdb of X sufficient? Do I need to set any variables to get better logs of the freeze? (This is a very random bug which can sometimes take days, would be nice to know just to be prepared. And I dont know much about kernel, hence the Qs.. :D )

That should be fine. The closest two kernels that where which have and don't have the problem are your best bet.
2 * Are there any pointers to narrow down the kernel commit from the backtraces I have posted? Or is just looking for "drivers/gpu/drm/radeon/" the closest?
You can narrow the bisection to just radeon, but if the problem is something non-radeon you'll get inconclusive results.
3 * Is there any specific command I need to run if I hit the bug? Or is gdb of X sufficient? Do I need to set any variables to get better logs of the freeze?
It's really hard to narrow down what causes the GPU to hang. It could be a bug in the kernel, it could also be a certain combination of command buffers or userspace acceleration drivers that happen to make the GPU angry. Just getting the commit id should be enough. You might also try a newer ddx and/or mesa 3D driver to see if that helps.

OK, sure will try that.
