Date: Sat, 26 Feb 2011 14:57:20 +0900 [thread overview]
Message-ID: <4D689640.8030906@lundman.net> (raw)
I apologies to bring up such an old kernel, but with embedded devices, I
do not have the ability to change kernel. I am trying to start
bluetooth, but I get a kernel panic. I have one device attached.
# insmod bluetooth.ko
# insmod l2cap.ko
# insmod btusb.ko
# insmod sco.ko
# insmod uinput.ko
# ./bluetoothd -d -n

Kernel panic - not syncing: Fatal exception in interrupt
I was hoping I could jog someones memory, and maybe get references to
some existing patches maybe, that I can apply to the kernel module by hand?
Thanks for any reply,
Lund
