hangs on dc(4) driver:
boot()
|
doshutdownhooks()
|
.... (indirect call)
|
dc_stop()
|
m_freem() on "RX list free" loop
(I suspect, incorrect or double release)

IAK> Other combinations works w/o problems.

>>>Fix:
IAK> Workaround: Replace NICs with another.
Q&D Fix: downgrade dc(4) driver:
dc.c 1.65 -> 1.63
dcreg.g 1.33 -> 1.31
(or downgrade to OPENBSD_3_4)
