Forwarding this bug from Ubuntu reporter jradwans: http://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/737110 [Problem] Another arrandale GPU lockup, but with IPEHR: 0x01820000. LP bug #725206 is similar with an IPEHR of 0x01800002; I don't know if that is significant, but presume it may be a dupe.

Thanks. I prepared a package for the user to test which includes this patch. After installing and testing it, they received another crash with the same IPEHR value: i915_error_state: Time: 1301810387 s 154509 us PCI ID: 0x0046 EIR: 0x00000000 PGTBL_ER: 0x00000000 Render command stream: ACTHD: 0x006e1014 IPEIR: 0x00000000 IPEHR: 0x01820000 INSTDONE: 0xffffffff INSTDONE1: 0xbfffffff INSTPS: 0x80000020 INSTPM: 0x00000000 Full details for this new crash are here: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/737110/+attachment/1971485/+files/xserver-xorg-video-intel.2011-04-03_07%3A59%3A49.020752.crash
Hmm, might be worth testing with Option "DebugFlushCaches" "True" and/or Option "DebugFlushBatches" "True" to rule out one possibility of a bad render op that lies uncaught till the wait.
No response from the reporter for testing those two options. But we've had three more bug reports come in with the same code, for various chips: 760068 [arrandale] GPU lockup (IPEHR: 0x01820000) 757399 [gm45] GPU lockup (IPEHR: 0x01820000) 752249 [q45] GPU lockup (0x01820000)
Given how often we have problems with this, we should probably include the pipe/plane regs in the error_state dump so we can see whether we're waiting for scanlines that will ever change.
