r300 PenumbraOverture complete hang 2.6.35/36-rc3 (regression)

r300 PenumbraOverture complete hang 2.6.35/36-rc3 (regression)

[PJBrs]

Hello, I'm experiencing a hard lock (i.e., no magic SysRq) after playing 
PenumbraOverture for about a minute on my ThinkPad t43p with kernel 
2.6.35 / 2.6.36-rc3. I'm using KMS. 2.6.34 works fine. I didn't test 
thoroughly with 2.6.35. With 2.6.36-rc3, I did not mess with any of the 
new power savings settings.

Some more info: lspci says:
ATI Technologies Inc M24GL [Mobility FireGL V3200] (rev 80)
System info: Slackware 13.1, Mesa 7.8.1, Xserver 1.7.7.

Has this bug (or one like it) already been reported? And if not, what 
can I do to be of help? Should I open a bug report, and if so, where? 
What further info do you need (kernel config, xorg.conf)? I can build 
and test new kernels, but I don't know how to bisect them. Also, I don't 
know how to gather a call trace.

r300 PenumbraOverture complete hang 2.6.35/36-rc4 (regression)

[PJBrs]

Hello,

Last week I reported a complete hang with PenumbraOverture on kernel 
2.6.35 and 2.6.36-rc3. This week I tried 2.6.36-rc4, and I still get a 
complete hang after playing PenumbraOverture for about a minute. I'm not 
using any xorg.conf, I'm using KMS. I also tried without KMS, and then I 
have no problem. 2.6.34 is the last kernel that worked with KMS.

I got no reaction on my first mail; could you please let me know whether 
this report is useful at all? And if so, could you please let me know if 
I should file this in Bugzilla? I searched bugzilla but I couldn't find 
anything like I'm reporting here. Also, this problem does not seem to be 
reported as a kernel regression.

Or maybe the problem is that I'm not subscribed to the dri-devel mailing 
list.

My graphics adapter is an ATI Technologies Inc M24GL [Mobility FireGL 
V3200] (rev 80), and I'm using Slackware 13.1 with Mesa 7.8.1, Xserver 
1.7.7. I wasn't able to get any further information--I tried running the 
game with all graphics options turned off, but it didn't help.

Anyway, I'd really like this problem to be solved, and I'd very much 
like to help out as much as I can.

PJ

Hi,

I missed this message when it was first sent. Could you check if this is
bug 29389 (https://bugs.freedesktop.org/show_bug.cgi?id=29389)?

The latest 2.6.36 RCs should already have the kernel parameter to
disable polling.
