Bug Description
Binary package hint: linux-source-2.6.20
Suspending works only once on this NC6400 notebook.
By default the first time doesn't work either, given that the i8042 driver must be compiled as a module, not in kernel, otherwise the keyboard won't work on resume (without echo -n reconnect > /sys/bus/
But, on the second time calling suspend I get this oops message about some NULL pointer:

I'm running Ubuntu Feisty with the following kernel (on core 2 duo T5600 laptop):

Some more info about my system.
It's an NC6400 RM100ET#ABH.
Attached is dmidecode and lspci -vv and lspci -vvn output.
