Hi,

Great news: only adding adding del_timer_sync() to 2.6.25-rc3 does prevent the crash.

Bad news: I still cannot use the device.

hcitool inq, hcitool scan, hcitool name <btaddr> and hcitool info <btaddr> 
commands work.

hcitool cc <btaddr>, sdptool <btaddr>, rfcomm connect command fail, most of them 
with a 'Connection reset by peer' error.

# rpm -q bluez-utils
bluez-utils-3.27-1mdv2008.1

Thank you,
