8.0R, AMD64 and wpi is giving me major grief

[Kurt Buff]

All,

I've got a Lenovo t61 with 4gbytes RAM that is giving me fits.

It's got a 3945abg chip in it, and it's getting really flaky. I can
boot it up, and work at the console for a while, and that seems to
work OK, usually.

However, today, when I start up my gui (xfce4), wireless just dies on
me. For a week before, it would usually run for a while (sometimes
days) before dying on me and requiring a reboot.

Below is a snippet of /var/log/messages - Does this mean anything to
anyone? Is there anything I can do to recover once this happens?

Thanks,

Kurt
