Sorry I can't somehow get my beagleboard to wake-up from suspend,
I'm almost certain that worked the last time I tried.

Anyways, maybe the following patch fixes this if you care to

It still crash.
The crash is different now.
It also complains about:
[   60.544224] Unbalanced enable for IRQ 65
Need down/up of the interface to recover after it.
