T30 bluetooth regression 2.6.20 -> 2.6.22

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I just tried a kernel from Ubuntu's Gutsy distro based on 2.6.22, and
compared to the Feisty kernel 2.6.20, I've lost the use of my Bluetooth
module. 

I have a T30 Thinkpad, and the Bluetooth isn't supported by the BIOS, it
complains at each bootup, but was working under 2.6.20 with

# echo enable > /proc/acpi/ibm/bluetooth

I checked thinkpad_acpi.c from 2.6.22.y branch of git.kernel.org and it
seems the new code detects the presence of the bluetooth modules solely
by the ACPI info.

Would it be possible or is there already a way to force
detection/enabling of bluetooth in 2.6.22?

Regards,

Jeremy
