i've got a single board computer with VIA C3 Samuel 2, 256MB RAM and 4
onboard Realtek 8139C+ NICs. I'm attempting to get FreeBSD 6.1-STABLE
working on them, but the realtek NICs just don't seem to want to work.
booting up led to a kernel trap with the following,
rlphy0: <RealTek internal media interface> on miibus0
rlphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto

processor eflags = resume, IOPL = 0
current process = 0 (swapper)
trap number = 12
panic: page fault

looking through /usr/src/sys/dev/re/if_re.c, and reading this thread,
http://lists.freebsd.org/pipermail/freebsd-current/2004-June/029373.html,
i've patched if_re.c to skip the re_diag() routine if the NIC is not a
Realtek 8169. the patch follows,

with the patch applied, the kernel trap goes away and the box boots up.
however, though the link light comes on, the device is effectively
unuseable for ethernet traffic. nothing seems to go in or out of the device
with ping and other tcp/udp traffic failing. note the media state and the
missing status line from the ifconfig output.
any clue as to what's happenning here or to pointers/patches to fix this
would be much appreciated. i've got the box sitting beside me, so testing
patches et al would be highly possible.
