Network adapter using sk driver needs a kick after reboots

[Laurence Tratt <laurie_(_at_)_tratt_(_dot_)_net>]

Synopsis: network adapter using sk driver needs a kick after reboots.
Severity: serious
Fix: Manual configuration of network settings.


I have an Asus P4P800 motherboard with a chip which uses the sk driver. On
the install disks, this works fine: the adapter connects to the network and
dhcp works fine. Upon all subsequent reboots of the installed OS, dhcp fails
to communicate with the network, and a simple forced ifconfig allocation of
IP address to the adapter doesn't work. No activity can be detected on the
network hub to which the adapter is connected. A subsequent "media
autoselect" after IP allocation gets things working again.

In other words, reboots of the machine following an install require the
following steps before network access works:

  ifconfig sk0 inet 192.168.0.6 netmask 255.255.255.0
  ifconfig sk0 media autoselect

Interestingly, if those two lines are put in a script and thus executed
immediately after one another, it doesn't work. It seems as if a pause
between the two is necessary. I haven't investigated how long this pause
needs to be: the delay caused by typing "ifconfig sk0 media autoselect" is
certainly sufficient. Manually trying to set the media type instead of using
autoselect doesn't seem to work, although I have not exhaustively tried this
option.

I have confirmed this problem with Jul 18 & Jul 30 snapshots on i386. My
dmesg is as follows:
