[Dell laptops] BCM2045B2 bluetooth adapter causes Ubuntu to fail to suspend/hibernate

[Aaron Kelley]

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.

Added Dell as I have a similar problem with my DELL M1330 (Dell Computer Corp. Wireless 355 Bluetooth); latest kernel (2.6.27-11-generic). Since this update the machine refuses to hibernate, returning to the locked screen box.
Here are the relevant dmesg entries:

removing Dell Ubuntu project as this is not a platform shipping with Ubuntu

[Leann Ogasawara (leannogasawara)]

Hi Aaron,

Just in case you be willing to test, the latest pre-release of Jaunty 9.04 (currently Alpha4) contains a newer 2.6.28 based kernel - http://cdimage.ubuntu.com/releases/jaunty/ . Unfortunately you can't test hibernate via a LiveCD, you can only test suspend. But please let us know your results if you do happen to update. Thanks.

Seems to be fixed in 9.04.
