Bad news, the kernel panics when I plug in the device on this kernel.
I compiled the kernel yesterday with default options except I changed
HZ=1000 and used generic X86_64 with kernel preemption:

$ uname -a
Linux zamserv 3.8.0-rc1 #1 SMP PREEMPT Sat Dec 22 21:56:06 EST 2012
x86_64 GNU/Linux

Attached is a panic dump.
