Excellent.

Not sure which driver that inhibits for you.  Still should be
investigated separately.

The patch doesn't re-enable polled mode during shutdown so those were
timeout messages.  I have a small revision to the patch that does this,
I just have to post it.

This is a separate issue.  Suspend/resume is not yet implemented on
amd64, nor is it implemented for multi-core machines.  Still, it should
not panic so I need to look into why that occurred.  The request should
simply be rejected as "not implemented".
