Under Fedora 14, my computer, an Asus U31J, cannot suspend/hibernate. It attempts both, but hangs and has to be hard powered off. (I have only tried F14.)
How do you debug something like this? I guess I'd need to have some tracing through the shutdown sequence to understand where it stops.

In case you used the pm-utils, consult the logs: /var/log/pm-powersave.log /var/log/pm-suspend.log
There is also script that can present you interesting information: # pm-utils-bugreport-info.sh
something useful can be also found in syslog: /var/log/messages
Test suspend from runlevels 3, 5 by: # pm-suspend and also directly through sys interface: # echo mem > /sys/power/state
If the last one fails from runlevel 3 it is probably the kernel and it will require more advanced debugging.
Please file bug about it. And also please try the F15, there are various improvements

That's how it looks. The machine clearly tries to suspend, but after a while the fan comes on at full power, so I suppose the processor is stuck in a tight loop.

OK, I will. Thanks.

The bug is still present in fedora 15.
