I have been getting a kernel bug in bluetooth startup. I'm running gentoo 2.6.8-r7. I have tried a fresh kernel, including a 2.6.8.1 version. Should this be reported as a kernel bug. How do I go about that?

this really looks like a kernel bug. Do you tried a 2.6.9 vanilla?

Hi Dave,

Quoted 3 lines

I haven't tried vanilla yet - I've built this kernel about 100 times, I guess once more won't hurt. Will have to wait till I get this box back into work where I have broad-band.

you must really try a vanilla one, because the vendor kernels are not really predictable. However you might wanna try to disable SMP and preempt and try again. If it not works then report this to the LKML, because this bug is in the VM and a way out of my knowledge.

Regards

Marcel
