I just tried that with 2.6.30-rc7, unfortunately it doesn't make any=20
difference.

It turns out that if I wait long enough (just over 1 minute) both durin=
g=20
suspend and resume, I *am* able to suspend and resume the machine. I ha=
ve=20
to manually turn it off or reset it though.

Another possibly interesting observation: My DVD writer apparently gets=

reset before the 1-minute hang and my USB hub after the hang.

Cheers,

  Richard
