Comment 20 for bug 715643

Tested pm-utils with a laptop containing a DW375 Bluetooth device. I ran a small, quick test of 20 consecutive S4 cycles with a 30 second delay between S4 iterations.

I was able to successfully complete all 20 without a hang in S4.

Without this 'fix', or some other workaround that disabled / enabled bluetooth during hibernate / thaw, the laptop would hang randomly and it rarely made it past 10 S4 cycles before hanging. Thanks, guys!
