[1.] One line summary of the problem:
Oops or panic when communicating through bluetooth.
[2.] Full description of the problem/report:
Computer is stable until using the bluetooth dongle to communicate
with a mobile phone. While communicating, most of the time it oopses
(computer still usable) or panics (can't even shift+pgup/pgdown).
Kernel is 2.6.12 from Debian Sid sources, but problem is probably
the same in vanilla kernel too.
[3.] Keywords (i.e., modules, networking, kernel):
bluetooth
[4.] Kernel version (from /proc/version):
Linux version 2.6.12-pluto-2-default-1-686 (root@dcerouter) (gcc version 3.3.5 (Debian 1:3.3.5-13)) #1 Thu Sep 22 05:29:23 EDT 2005
[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)
(taken from syslog)

[6.] A small shell script or example program which triggers the
problem (if possible)
#!/bin/bash
MAC="$1" # Mobile phone's MAC
SIS="$2" # File to upload to phone
(echo "c"; echo "p"; echo "$SIS PlutoMO.sis"; echo "q") | obex_test -b $MAC 9
# obex_test is a console bluetooth utility found in package
# openobex-apps in Debian. It connects to the phone and, with the
# commands in the subshell, it sends a file to the phone. That's when
# it dies
