Hello, I hope this goes to the correct mailing list:
I've observed a freeze today in i8xx_enable_fbc(), module i915 with vanilla Linux 2.6.32.5 running on my Eee PC 1000HG. Kernel log and config is attached.
Strangely, this happend just the instant I was going out of scope of wifi hotspot. Could be coincidence...
If you need some more information, just ask. Cheers! Thiemo Nagel
