Just went that path, compiled 2.6.37-rc4-00292-g3c8cdf9
and suspended which resulted in a completly dead device
(no ping, no ctrlaltdel possible), i.e. different fatal situation.

I'm a bit confused, not sure whether this is related to
the broken display issue or not.

As the tests always cost a quite lengthy fsck run, I'd
love to go a different way from 2.6.37, if anybody has
a better hint.

Cheers,

Nico
