Has anyone else been having problems with a wi0 card periodically
hanging?  I've got a:
wi0 at pci2 dev 3 function 0: Intersil Prism2.5 Wireless Lan
wi0: interrupting at irq 10
wi0: 802.11 address 00:09:5b:40:b7:de
wi0: using RF:PRISM2.5 MAC:ISL3874A(Mini-PCI)
wi0: Intersil Firmware: Primary (1.0.7), Station (1.3.6)
wi0: supported rates: 1Mbps 2Mbps 5.5Mbps 11Mbps

which gets errors that look (exactly) like this:
wi0: timeout in wi_seek to 13d/0

When this happens the card hangs for a while.  Recently (since the
last reboot, no kernel change (1.6W, Aug 13)), it has stopped with
the messages, but still hangs.  Running an "ifconfig wi0 down up"
seems to get it back up faster, but the 'up' part of that ifconfig
take a while to run (a few seconds, vs instant for e.g. wm0)
	I've since updated to 1.6Z, with no change in behavior.
