I added myself to that bug, though I wasn't really seeing that much of
a slow down in graphics. (I have an rv280 which might not have the issue
that later radeon cards were having.) My issue seems to be related to
disk I/O. I am not sure if it is heavier cpu use in journalling, raid or
encryption or if the actual I/O is slower. But it seems that I/O heavy
activities such as yum updates and kernel builds are taking several times
longer than they were a few weeks ago (in rawhide).
