There's a slew of uhub messages, so presumably _something_ in the PCI
space is getting probed; the last couple of messages before things crash
are:

isapnp0
npx0
pcppi0: attached to cttimer0
isapnp: No Plug 'n' Play devices
index IRQ Rtd Ref IRQs
(LNK[A-D] messages)
(freeze)

Unfortunately, this thing has no serial ports, so it'd be difficult to
grab the dmesg that way.
