Re: kernel panic while copying files

I was sort of hoping that all the recent changes made by imp@ in cam and
umass may have fixed the cause of the kernel crash.

Unfortunately not.

But there is a change - instead of a duplicate free the panic is now the
result of an unaligned free.

panic: Unaligned free of 0xfffff800259e2800 from zone
    0xfffffe00dc9d2000(da_ccb) slab 0xfffff800259e2fd8(3)

I have the crash dump and a debug kernel in case anyone wants more info.
