Ok, sounds like it's failing to actually suspend. The easiest thing to
do here is probably to edit /etc/acpi/hibernate.sh and add

dmesg >/root/dmesgoutput; sync

just underneath the 

echo "disk" >/sys/power/state

line. After attempting a suspend/resume, you should have
a /root/dmesgoutput file which will contain the trace from the suspend
attempt. If you could send me that, that would be great.

That's very strange. Could you do something similar
with /etc/acpi/sleep.sh ?

Thanks,
