Daniel, the test did not go well. Lots of "*ERROR* Timed out waiting for
forcewake to ack request." and crashes, most like the report in my previous
post.

However, while compiling that kernel version I've continued to use the last
kernel from git (
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git) with the
patch from Rodrigo (#55, https://bugzilla.kernel.org/show_bug.cgi?id=43267#c55)
and also running glxgears, as commented in previous post. This makes for an
accumulated uptime of nearly 5h without any single symptom of the bug. The
patch was not fully applied (rejected files are in my previous attachment), but
I believe it is worth to look at what was applied, because it is the only
difference between my report with crashes and 5h of calm.

Anyway, I will continue to work with that patched kernel to accumulate more
uptime.
