--- Comment #9 from gitne@excite.co.jp --- (In reply to Michel Dänzer from comment #8)
Can you attach the kernel log from before and across suspend/resume as well?
I can try but there seems to be nothing worth noting before resume. Is there any kernel boot parameter or a radeon module parameter that I can tune to get a more verbose kernel log? I'll try running on my latest F21 kernel version 3.19.5 but I doubt I'll see any improvement, judging by the changelog.
Best regards
