<pre>I looked back through kern.log and found the last time I encountered a crash,
which happened to be with kernel 3.15.10 from the Ubuntu repo.
That crash seemed to have been caused by dpm:
[drm:si_dpm_set_power_state] *ERROR* si_set_sw_state failed
The 3.15.10 version isn't part of the source, so I instead looked through the
list of changes and found that the last set of changes made to drm, landed in
kernel 3.16-rc6.
So I installed the rc6 image and has now been running it for some time, but ran
into yet another issue, which is unrelated to this bug.
[ 6533.114483] alloc_contig_range test_pages_isolated(1bc800, 1bca8c) failed
[ 6533.114492] alloc_contig_range test_pages_isolated(1bc800, 1bca8d) failed
[ 6533.114500] alloc_contig_range test_pages_isolated(1bc800, 1bca8e) failed
[ 6533.114506] alloc_contig_range test_pages_isolated(1bc800, 1bca8f) failed
[ 6533.114511] alloc_contig_range test_pages_isolated(1bc800, 1bca90) failed
[ 6533.114516] alloc_contig_range test_pages_isolated(1bc800, 1bca91) failed
And so on.
It pretty much causes frequent 2-5 second hangs, even while I'm writing this
message. Just moving the cursor, causes such a hang. Changing workspace and the
hang lasts 40 seconds.
In other words, bisecting the dpm issue would be very difficult, since I would
more than likely run into this issue as well.
The last change made to drm/radeon/dpm were merged into 3.16-rc1, and it only
affect si hardware.
Suppose this issue could be moved to another bug entry, if it hasn't already
been fixed.</pre>
