Hi,
Just got below error on Ubuntu-11.10 (kernel: 3.0.0-12-generic), and after that my screen can't show normally. No sure if it's a known issue.
[169509.080020] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung [169509.080026] [drm] capturing error event; look for more information in /debug/dri/0/i915_error_state [169509.080604] [drm:i915_wait_request] *ERROR* i915_wait_request returns -11 (awaiting 1640573 at 1640569, next 1640574) [169509.080688] [drm:i915_reset] *ERROR* Failed to reset chip.
BTW, dmesg and i915_error_state and lspci is attached.
Thanks, Yong

No, that is the first time I've seen that. It looks as if the fence was not released, or reacquired, before the the batch was executed. (There is a later batch that also uses this buffer.)
The fence is programmed with: fence[15] = 04e00001 valid, x-tiled, pitch: 512, start: 0x04e00000, size: 1048576
And the BLT command uses: 0x0df006b0: 0x54300004: XY_COLOR_BLT (rgb enabled, alpha enabled, dst tile 0) 0x0df006b4: 0x03f00100: format 8888, pitch 256, clipping disabled 0x0df006b8: 0x00000000: (0,0) 0x0df006bc: 0x00140037: (55,20) 0x0df006c0: 0x04e00000: offset 0x04e00000 0x0df006c4: 0x00000000: color 0x0df006c8: 0x54f00006: XY_SRC_COPY_BLT (rgb enabled, alpha enabled, src tile 0, dst tile 0) 0x0df006cc: 0x03cc0100: format 8888, dst pitch 256, clipping disabled 0x0df006d0: 0x00000000: dst (0,0) 0x0df006d4: 0x00140037: dst (55,20) 0x0df006d8: 0x04e00000: dst offset 0x04e00000 0x0df006dc: 0x012c0003: src (3,300) 0x0df006e0: 0x00000400: src pitch 1024 0x0df006e4: 0x08500000: src offset 0x08500000
So we try to perform an undefined operation and the GPU hangs. I suspect this will be timing dependent, but if you can find a way to reproduce it, that would be very useful. -Chris

Just got it by accident when I'm browsing web with firefox & chromium, and the machine has been running for a long time.
No reliable way to reproduce it for now :(
