Subject: Kernel BUG from tegra_dc_irq()
Date: Fri, 12 Dec 2014 17:30:43 +0900 [thread overview]
Message-ID: <548AA7B3.7080400@nvidia.com> (raw)
Hi Thierry,
I sometimes notice the following oops happening. Generally when I am
running Weston/glmark2 for long periods of time (at least 4/5 hours). I
am trying to see if I can reproduce it with simpler workloads. Are you
aware of this?
Cheers,
Alex.
