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.
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.
Please file bug about it. And also please try the F15, there are
various improvements
OK, I will. Thanks.
Andrew.
