6-STABLE, ath, wpa_supplicant/dhcp and suspend/resume problem.

[George Hartzell]

I have an IBM T42p (2379-DYU) with an atheros based mini-pci card,
running 6-STABLE cvsup'ed yesterday morning.

I have wpa_supplicant configured for my WEP based 11g network, and
have this line in my /etc/rc.conf:

  ifconfig_ath0="DHCP WPA NOAUTO"

I start the interface via /etc/rc./netif start ath0 when I want to use
it.

When I suspend the laptop, the wireless link doesn't work on resume.
The little icon in my gnome panel has a red disk/white line across the
transmit/receive graphics, but the signal strength indicators are a
3-high pile of diamonds (same as when it's working).  I'm not sure
where the panel-thingy is getting its information.

I can resurrect the interface w/ /etc/rc.d/netif restart ath0.

When I run wpa_supplicant by hand with some debugging flags, I see the
following:

And the interface isn't working.  Killing and restarting
wpa_supplicant brings it back.

I also have an older apm based sony Z505 w/ an ath0 pc-card that
suspends and resumes w/out any manual intervention.

What can I do to make the IBM work w/out manual intervention?
