Subject: Re: [3.14 regression] kernel oops with dpm enabled on TURKS

mmm further tests shown the oops was casual, maybe related to the real
problem, I can't say. I'm unable to reproduce it.
But the gpu stall is 100% reproducible with dpm enabled. Attached is the log
that usually shows up. Other than that, I also observe the lspci "Unknown
header type 7f" problem similar to ko bug #73041
https://bugzilla.kernel.org/show_bug.cgi?id=73041
A few notes:
- I can confirm that the problem was first introduced by
6c7bccea390853bdec5b76fe31fc50f3b36f75d5. Until
e14cd2bbcb98541e199b7223f38d61527dfe45c9 the gpu works.
- The "Unknown header type 7f" thing is not new to me. I experienced this
problem a year ago, trying the Catalyst driver. I spent some time filing a bug
report for amd, which remained unanswered:
http://ati.cchtml.com/show_bug.cgi?id=743
Alex, do you have any clue? Maybe your commit changed something into the
initialization order which is confusing this gpu?
Thanks,
Giancarlo
