wpi works as long as one doesn't do anything that saturates the wlan
connection. E.g. running ssh terminal sessions is fine, but trying to
scp a bigger file crashes the machine instantaneously.

On my machine (and some more, as reported in another thread) ath
freezes when hal is running. As a workaround removing the card during
bootup helps. It has just to be configured manually.
