PCI hme and nsphy on my Ultra5 sometimes fails autonegotiation
between switching hub during boot. The attached patch from OpenBSD
seems to fix the problem, but does anyone else see the similar problem
on U5 and PCI hme?

OpenBSD's log message said:
http://www.openbsd.org/cgi-bin/cvsweb/src/sys/dev/mii/nsphy.c
Revision 1.3:
 :
o hme doesn't advertise everything it supports, so
  during reset, set the ANAR according to the supported media in BMSR.
