Hi,

I'm Jan and I'm new to this list.

So here is my problem.

I activated sleepstates in my Kernel 2.6.9 and when I type echo -n "mem" 
 > /sys/power/state my R51 (2778-32G) suspends to ram properly. When I 
wake it up by pressing Fn+F4 it fully comes up but the screen stays 
black. No reaction not even the backlight is going on.

I can use it 'blind' and do everything but I can't see anything.

So I sshed to it and took a look at the log-files:

Oct 22 18:47:43 [kernel] eth1: Going into suspend...
Oct 22 18:47:44 [kernel] MCE: The hardware reports a non fatal, 
correctable incident occurred on CPU 0.

Oct 22 18:49:12 [kernel] Unable to handle kernel NULL pointer 
dereference at virtual address 00000000

I couldn't find any usefull information with google, so could you please 
help me?
Seems like a kernel-problem to me. Propably just a bad configuration.
Should I post my .config here?

nice evening
Jan
