Instead the advice is to update the register using the MI_LOAD_REGISTER_IMM command. In cursory testing, semaphores continue to function - the question is whether this fixes some of the deadlocks where the semaphore registers contained stale values? hopefully addresses. That patch is only available on drm-intel-next at the moment, which is available either at http://cgit.freedesktop.org/~danvet/drm-intel or available as drm-intel-experimental in the ubuntu kernel-ppa.

I have H61M/U3S3 motherboard and you latest BIOS ver 2.20 from 8/15/2012 ftp://174.142.97.10/bios/1155/H61MU3S3(2.20)ROM.zip How to check problem persists or not?

Rendering throughput is dropped by 10% with SNA, or as much as 3x with UXA. OpenGL performance is likely to be reduced by about 30%. More CPU time is spent waiting for the GPU with rc6 disabled, so increased power consumption.
