I have the same problem since 2.6.34. The above hack fixes it for me (tested
with 2.6.35.7 and a few earlier 2.6.35 releases, in frequent use for more than
a month now), while the patch from comment #82 does not help in my case (last
freeze was while using the search bar of firefox).
Video chip is a:
01:00.0 VGA compatible controller: ATI Technologies Inc RV350 [Mobility Radeon
9600 M10] (prog-if 00 [VGA controller])
Subsystem: ASUSTeK Computer Inc. Device 1772
Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 11
Memory at d0000000 (32-bit, prefetchable) [size=128M]
I/O ports at d800 [size=256]
Memory at ff8f0000 (32-bit, non-prefetchable) [size=64K]
Expansion ROM at ff8c0000 [disabled] [size=128K]
Capabilities: [58] AGP version 2.0
Capabilities: [50] Power Management version 2
Kernel driver in use: radeon
With the updated patch I get these messages:
