Summary: Random system freezes with RV350
Product: xorg
Version: git
Platform: Other
OS/Version: All
Status: NEW
Severity: critical
Priority: medium
Component: Driver/Radeon

Hello, I get random system freezes using:
Ubuntu 9.10 Karmic (Beta)
xserver-xorg-video-radeon from Tormod Volden: 6.12.99+git20091002.cc45856a
Toshiba M30X with an ATI Radeon 9700 (M10) - RV350 - 64 MB VRAM
The freezes seem GPU hardlocks, mouse pointer is frozen too and keyboard stops
responding (no Caps Lock, no SysReq magic keys); ATM I cannot if system is
accessible via ssh (I suspect yes, though). As said, system hardlocks randomly;
anyway, more often the freeze is triggered by:
* window maximize/minimize (more often with compiz enabled)
* evince pdf reading (compiz enabled and disabled)
Increasing virtual size makes crashes more frequent, using multiple monitors
with xrandr is a guaranteed crash. This makes me think that the issue can be
related to VRAM amount and/or GART transfers (I don't know the matter so well,
actually...).
The only way I found to stop freezes is setting RenderAccel to false, but then
I get screen corruption increasing virtual size beyond the default (greater the
virtual is, greater is the corruption). And obviously the system becomes
noticeably slower...
Options like AccelDFS, AGPMode=[PCI|auto|1] (set via xorg.conf and via
modprobe), ClockGating, DynamicPM, dynclks seem to not make difference.
