>Description:

Running NetBSD-current/i386 on a Fujitsu-Siemens Amilo Pro V3205
laptop, whose built-in WiFi device attaches as wpi0, when I run
the following commands as root:

  ifconfig wpi0 up
  while true; do ifconfig wpi0 list scan; done

it successfully completes a few scans but then logs

  wpi0: fatal firmware error

and stops scanning.  I can get a shell prompt back by typing
control-C; at that point, the interface is down, but if I run both
shell commands again, it once again completes a few scans before
failing as before.

>How-To-Repeat:

See above.
