Good call! ASRock's website doesn't appear to have direct links to older BIOS versions, but if you guess the links, and it turns up these versions: http://download.asrock.com/bios/1155/H67M(1.60)WIN.zip http://download.asrock.com/bios/1155/H67M(1.70)WIN.zip http://download.asrock.com/bios/1155/H67M(1.80)WIN.zip So if someone has an older revision B2 chipset they can try these versions. I RMA'd my board (given that it /was/ recalled because of the SATA issues) and got a new B3 chipset that supports Ivy Bridge and has BIOS v2.10. No more rc6 failures with this board. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1020733 Title: [sandybridge-m-gt2+] GPU lockup IPEHR: 0x78170003 Status in X.org xf86-video-intel: Invalid Status in “xserver-xorg-video-intel” package in Ubuntu: Triaged Bug description: I had a projector connected, suddenly everything exploded.
