| |
The drm-intel tree just updated to 3.13-rc, and I started seeing early hard hangs on my BYT system. I bisected it down to this commit:
commit 19e77c28dbf1972305da0dfeb92a62f83df3a91d Author: Dirk Brandewie <dirk.j.brandewie@intel.com> Date: Mon Oct 21 09:20:35 2013 -0700
intel_pstate: Add Baytrail support
Add support for the Baytrail processor.
The hangs occur at different times, so unless the get/set functions aren't called until we change the state, the problem may be in the core_set_pstate function instead? Maybe it's not suited to BYT somehow?
Thanks, -- Jesse Barnes, Intel Open Source Technology Center
