reloading HAL drops ra0 from network Manager, then segfaults

When HAL is reloaded, during package installs or via etc/init.d/hal restart , the interface ra0 disappears from network-manager. After a while, network-manager usually segfaults.

from /var/log/daemon.log:

Hard to say if this is a NM 0.7 - bug or a eeepc_laptop - bug.

iwconfig shows ra0 existing

lsmod shows rt2860sta is still loaded
