Title:
[Dell laptops] BCM2045B2 bluetooth adapter causes Ubuntu to fail to
suspend/hibernate
Status in The Somerville Project:
Invalid
Status in “linux” package in Ubuntu:
Fix Released
Bug description:
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.
