Hi all
Sorry, not sure what information is most appropriate here. GPU hangs from time to time on this laptop, typically when running firefox on graphics-intensive sites. Error log at the bottom. Distro is Debian 6.0.6 (squeeze), lspci
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 03) (prog-if 00 [VGA controller]) Subsystem: Acer Incorporated [ALI] Device 011f Flags: bus master, fast devsel, latency 0, IRQ 46 Memory at fc000000 (64-bit, non-prefetchable) [size=1M] Memory at d0000000 (64-bit, prefetchable) [size=256M] I/O ports at 1800 [size=8] Expansion ROM at <unassigned> [disabled] Capabilities: [90] MSI: Enable+ Count=1/1 Maskable- 64bit- Capabilities: [d0] Power Management version 3 Kernel driver in use: i915
kernel version 3.5.2 (yes, I'll try to upgrade). Sometimes also the X-server freezes and restarts with no errors in dmesg. Is it a known problem?
