Install the debian firmware package.
The bug summary is wrong. The warnings about firmware were artifacts from debugging in a minimal environment (to rule out other some other driver causing the hibernation trouble).

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*)?
