This is more serious than just a bnx issue. I can't see how a
XENMEM_decrease_reservation can fail, unless it gets passed nonexistent
pages. Can you try booting xen-debug.gz instead of xen.gz, and see
if xen has something to say about this XENMEM_decrease_reservation
operation (should appear just before the NetBSD kernel reports that
it failed).
