Hi Stephen,
I've noticed a rather strange problem with the onboard sky2 on one of my
machines. When I halt -p it, my router stops passing traffic completely
until I kill the power to the machine entirely. If it's just been shut
down with halt -p, it recovers immediately after turning it back on,
while it's in BIOS.
Any thoughts on this? My guess is its because the sky2 shutdown puts the
nic to sleep and when the host is off, bad things happen.
regards, Kyle

The sky2 shutdown puts the chip in Wake On Lan state; this
does a separate link speed negotiation (100 mbit) which may be a problem
if speed duplex is forced.

Hrm, I'd disabled WoL in ethtool explicitly hoping this sort of thing
could be avioded, but it doesn't seem to help. :/
I'm not sure what you mean by "if speed duplex is forced," I've left the
nic in autoneg mode.
