I'm too seeing these annoying kmem_malloc panics on recent -current
kernels. The laptop I'm using is way off of being overloaded at all, the
only thing I do is going online using a Bluetooth USB dongle. As soon as I
generate some network traffic, devbuf allocations go up, until at some
point the machine panics randomly in kmem_malloc.

I have different core dumps and backtraces available, but they don't seem
to be of much use in this case. I really suspect the USB stuff to be
leaking.
