Public bug reported:
I am using a Dell Inspiron 1720 notebook with Ubuntu 8.10 x86_64. I
have been having intermittent hibernate failures (I'd say about 1 in 4
attempts fail) and I tracked it down to the bluetooth adapter not
suspending properly. The bluetooth adapter is a Broadcom BCM2045B2.
Here's a snippet from the syslog around a failed hibernate:

Notice the failure notifications on lines 6, 9, and 11. Device 1-2 the
bluetooth adapter.
When the hibernation fails, I am plopped back at a screen asking for my
password to unlock my desktop session. It is as if the hibernate was
successful and the machine had been turned back on (however, the machine
never actually turned off).
Let me know if I can provide any additional information.
