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?
Today I am using kernel 3.2.0-2-amd64 . The problem still exists in exactly the same way - the first hibernate always works perfectly fine - the second hibernate causes system hangup. After this long time I am not sure if I remember all the checks to do. Maybe also some things changed in the newer kernels ;-) What I did is:
- start system with option "break=bottom" - in the shell coming up, lsmod shows that radeon driver is not loaded - hibernate check works fine three times in follow
But at this point I do not know how to load the radeon driver cause "modprobe radeon" brings up error message "module radeon not found in modules.dep", so I cannot tell if radeon has the same error message as last year.
By the way - don't know if you are concerned by this - but I also received a mail from a guy at bugzilla.kernel.org asking if the problem still exists - but my answer mail could not be delivered to him 4 times because of the following server problem :" The following addresses failed: bugzilla-daemon@bugzilla.kernel.org host bugzilla.kernel.org[198.145.19.204]: connection to mail exchanger failed"
