When trying the "drm.debug=0x6" and "no_console_suspend" parameters the system sometimes didn't hangup on hibernate test - the test worked 3 times in follow without hangup. And second suspend to disk with the two parameters did not really suspend - the power led continued to burn as described above - and the screen turned to power safe mode - but after a second or two the screen powered up again and showed the login screen of suspend mode. But this could not be reproduced constantly - strange!
Do you have logs from when this happened (they might be somewhere in /var/log/dmesg*)?
Please find attached all the /var/log/dmesg* files with their timestamps in ls.txt .
That isn't quite what I meant. The timestamps aren't so helpful to us since we weren't there; we can't easily tell which suspend you are talking about.
What kernel are you using these days? Does it still fail to hibernate when the radeon driver is loaded?
