glxinfo

I am having a hard lockup with r300g when playing Penumbra Black Plague game ( a free demo is available via http://www.penumbragame.com/demo.php ), or when playing flash content with lightspark.

Card   : ATI Mobility Radeon X700 PCIE ( RV410 )
Kernel : 2.6.35.6-37.fc14.i686
driver : xf86-video-ati-6.13.2
mesa   : d6e2b707baecb7655cd09d64080fc944cc5704a6 , built with Fedora spec file
glxinfo: (attached)

I am sorry for filing this bug with this few information, but the hard lockup left me out of options.

Could you please try latest kernel 2.6.36-rcN? There are some hardlock fixes.

Please see also bug 29389, which describes another possible cause of hardlocks with a workaround. There is also bug 28474, where user Tormod Volden had had hardlocks with the same GPU as you and the workaround in bug 29389 helped him.

booting 2.6.36-0.41.rc8.git5.fc14.i686 with drm_kms_helper.poll=0 fixes the lockup for me
