Details of the panic:

ral0 detached.

uvm_fault(0xc0690040, 0xcb182000, 0, 2) -> 0xe
kernel: page fault trap, code=3D0
Stopped in pid 14.1 (aiodoned) at    netbsd:ral_intr+0x13e: movl
$0xffffffff,0x20(%ecx)

The trace goes as follows:

uvm_aiodone_daemon
uvm_aio_aiodone
Xspllower
--- interrupt ---
Xintr_legacy10
pccbbintr_function
ral_intr

(backwards).

...if that is of any help; I may compile a debug kernel to see if I
can gather something more.
