This may be related to rc6 since that if I add i915.i915_enable_rc6=0 to boot parameter then this issue is gone. This issue also happens on kernel 3.4. A screenshot when system hangs: https://launchpadlibrarian.net/105661463/Photo%2012-5-18%2017%2038%2038.jpg If there's any other information needed, please kindly let me know. Thank you.

Also, how dead is the system? I.e. does network/ssh still work, does the magic SysRq to reboot still work, or is it a true hard-hang? And can you try to wire up netconsole so that we could have a peak at the last breaths of the system before it goes down?

When it hangs, neither SysRq magic nor network/ssh works. From ssh terminal I can tell that it died after 57 minutes, but the last entry in the log is at 1787.315652, so there's no log when the system goes down.

We still need to load the drm/i915.ko driver, because only when we load and enable rc6 can the cpu die actually reach the lowest power state, i.e. I want to check whether this might be an issue outside of the gpu, only brought to light due to the low power state.

Try something like adding blacklist i915 to modprobe.conf, or append i915.noload to your kernel commandline.
