But it doesn't "know" to fail until after you pull the USB plug if I
understood you? So it should have been asleep OK?

Wah I didn't know you were in .tw.
What annoys me about these resume problems is I put special code in to
dump nicely on serial console if it ever OOPSed, it never OOPSes.
This code is handy because it does the serial traffic without needing
serial devices out of resume.
If you get to thinking it can help, dropping this somewhere should get
you a dump of syslog so far and a stack trace, you can maybe move it
around and see how far it is resuming...
extern int global_inside_suspend;
extern int oops_in_progress;
oops_in_progress = 1;
global_inside_suspend = 1;
Another idea is stick that in the AUX key interrupt if that is
operational by then, and / or disable the disable of it on suspend.
