Could this be a workaround for my bug as well (disconnects caused by
scan while associated)? I get the following log entries:

I isr_status_change Scan detected while associated, with no scan
request.  Restarting firmware.=20
I schedule_reset wifi0: Scheduling firmware restart (0s).=20
I isr_status_change Status change: IPW_STATE_SCANNING=20
I isr_indicate_scanning Scanning...=20
U ipw2100_reset_adapter : wifi0: Restarting adapter.=20
U ipw2100_power_cycle_adapter Power cycling the hardware.

I only have 1 AP, though.

Cheer,
