When you upgrade openSUSE 12.1’s KDE 4.7 to 4.8 (using this repo), suspend to disk or ram might stop working. If so, you’ve encountered bug 758379: STR (Suspend to RAM) fails when NetworkManager running and NFS shares mounted
The description is a bit misleading. It also happens for suspend to disk (STD) and when you don’t use NetworkManager.
Workaround: Unmount your NFS shares before you try to suspend:
sudo umount -t nfs -a
If you use NFS v4, then the command is:
sudo umount -t nfs4 -a
To check whether it worked, use this:
mount | grep nfs
This shouldn’t print anything with “type nfs” anymore. Afterwards, suspend should work.
