Subject: Regression: hang on BYT with new pstate support
Date: Fri, 6 Dec 2013 10:56:56 -0800 [thread overview]
Message-ID: <20131206105656.4c4b1e5e@jbarnes-desktop> (raw)
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>

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,
