Comment 22 for bug 92461

I still have the problem with my t42 with latest release...

Nevertheless, I found a workaround :
Install uswsusp
edit /etc/uswsusp.conf to add/change :

early writeout = y
shutdown method = shutdown

and the enjoy s2disk...

If one of these 2 lines is not set, the s2disk does not work (same behaviour than with /etc/acpi/hibernate.sh)
I hope it will help...
