Hi, I forgot to mention that I'm running on a crypted disk. So
"init=/bin/bash" fails. But I booted kernel-2.6.29-0.41.rc2.fc11.i686
using "1" as a kernel parameter, and put the laptop to suspend by
# echo -n mem > /sys/power/state

But still, I was not able to resume it - black screen, keyboard dead.

Could it be related to my disk encryption? I though "everybody"
encrypted their laptop these days?
I set it up during installation (full disk encryption, I get prompted
for passphrase as the first thing during boot).

This is my layout:
# df -h

12G 7,5G 4,5G 63% /

I'd be happy to test further - please let me know what info I can provide.
