Date: Thu, 17 Nov 2011 09:57:09 +0100 (CET) [thread overview]
Message-ID: <1437314987.3618076.1321520229356.JavaMail.fmail@mwmweb014> (raw)
Daniel,
your ppgtt branch commit hardlocks my machine (SNB Mobile GT2+) as soon as I fire up X with a black screen. No crashdumps/syslogs :( Kernel params are: intel_iommu=off pcie_aspm=force i915.i915_enable_rc6=1. neither i915.semaphores=1 changes that nor does dmesg yield anything fancy.
Regards,
Nic
