It has helped and the laptop is able to suspend with the serial cable 
attached (further than before). It now panics on the first resume with 
the following (gdb output at bottom).

I think the serial cable is masking the problem as without it I can 
suspend/resume once and it only panics on the second resume. I guess I 
need the serail working to see that panic anyway.
