Subject: PROBLEM: Bluetooth crashes system
PROBLEM: Bluetooth crashes system
My smartphone sometimes reboots because of overflowing of memory. Sometimes after it bluetooth does not work. Wvdial (and other dialers that i tested - simple pppd, pon/poff, kppp) simply freezes after it. I can not kill it by `killall wvdial` or `killall -s 9 wvdial`.
I found that it prints following strings to kern.log:

Now I am using ASUS BT-211 (ath3k kernel module), but i got the same bug with other bluetooth adapters.
Keywords: modules, bluetooth, crash
I use Debian GNU/Linux 5.0 (with updated kernel). Now I am using experimental prebuilt 2.6.35-trunk kernel, but i had the same bug with 2.6.32 from squeeze and with 2.6.34 vanilla. I did not use git bisect because i have slow internet (i can not download git kernel tree) and i need much time to reproduce this bug. But I detected that this bug does not affects 2.6.26 and older (but now i can not use it - ath3k are only supported by 2.6.33 and newer).
