Maybe.

Just made another test: the machine (macbook) woke up, loaded image, thaw.
It got stuck at vt#1, displaying console with login. Cursor blinking, but
no (usb) keyboard or network enabled. Bricked?!!


On the other hand I've got another box with nvidia gpu:

debian5 32bit
2.6.38.2+ #3 SMP Fri Apr 1
nvidia 260.19.36

It's up since I compiled the kernel: I use it twice a week and I kept it
freezed all the time. It was solid rock until today: hard reset on resume.
WTF? (I remember this version combo was stable on the macbook but the
kernel lacks a solid wireless driver).

There are a stupid situation where you can't debug. What else can go
wrong? This is off topic but it's a cute kernel crash while I gave the
nouveau driver a chance:
