I tried the suggestions that worked for the original poster (psivaa) and
they didn't work for me. So I think I have a different bug. Still hangs
in suspend or hibernate. The screen goes black, but then there's high
fan speed and no way to get out except manual power down. I don't know
if I should file a new bug report or how to do that yet.
details of workarounds I tried:
1. editing etc/default/grub
(a) "quiet splash xforcevesa" (suggested elsewhere for generic video cards) =>
same hang
(b) "quiet splash no_console_suspend" then $ sudo pm-suspend => same hang,
difference noticed on startup: a blinking cursor at 800x600 mode home position
just after OS selection instead of black screen during that part of startup
(c) "acpi=off radeon.modeset=0" => same hang on hibernate, "suspend" removed
from logout menu
2. commands suggested in #14 (and etc/default/grub back to original "quiet
splash")
$ echo 0 | sudo tee /sys/power/pm_async
$ sudo pm-suspend
=> similar hang, except fan stayed off instead of going to higher speed as it
did during other hangs
