>Description:
This is the relevant dmesg output:
....
pcic0: <Ricoh RL5C475 PCI-CardBus Bridge> mem 0xef005000-0xef005fff irq 3 at device 3.0 on pci2
pccard0: <PC Card bus (classic)> on pcic0
....
pccard: card inserted, slot 0
pccard: card removed, slot 0
pccard: card inserted, slot 0
wi0 at port 0x240-0x27f irq 3 slot 0 on pccard0
wi0: 802.11 address: 00:60:1d:aa:bb:cc
wi0: using Lucent Technologies, WaveLAN/IEEE
wi0: Lucent Firmware: Station 8.10.01

After setting any parameter for wi0 with wicontrol subsequent launches of wicontrol will sporadically fail with the following message: wicontrol: SIOCGWAVELAN: Invalid argument. From that moment the system will sporadically freeze for 1-2 seconds reporting "wi0: wi_cmd: busy bit won't clear." at the system console.


>How-To-Repeat:
wicontrol -i wi0 -f 1

wicontrol -i wi0
reports "wicontrol: SIOCGWAVELAN: Invalid argument"
(Might take several attempts to show up)

From that moment the system sporadically freezes for 1-2
seconds with the following messages at the system console:
wi0: wi_cmd: busy bit won't clear.
wi0: wi_cmd: busy bit won't clear.
wi0: wi_cmd: busy bit won't clear.
