Can't shutdown or restart after computer was suspended

I upgraded my Lenovo T520 from opensuse 12.2 to 12.3 using zypper. When I start computer then restart or shutdown works correctly.
But after suspend to RAM and wake up it doesn’t work and it freeze on shutdown phase.
Any hints?

thanks, miso

One thing you could try is to press Ctrl-Alt-F1 (or Ctrl-Alt-F2, …, Ctrl-Alt-F7 usually brings back the original session),
then login as root, and then say

shutdown -h now

This isn’t really a cure, but it may help to avoid to just cut the power.

Good luck
Mike
