Hi,

I have compiled linux kernel 2.6.23.8 for a single board computer based
on ARM architecture (EP9302 processor). I have tried to stress the
Bluetooth subsystem, creating repeatly a lot of RFCOMM connections to
other Bluetooth dongles (installed on remote computers) and I'm able to
get a kernel panic in few minutes.

Unable to handle kernel paging request at virtual address 57ac5e8c

I have also attached the system log. I hope it helps.
