iwm0 firmware issue

[Robert Nestor <rnestor%mac.com@localhost>]

I’ve been running -current on a new laptop and have installed a number of snapshots since 7.99.59.  With the 7.99.67 snapshot I’m seeing the message “iwm0: fatal firmware error” occasionally on boot.  There is no other information on this that I can find and obviously at that point the network device isn’t usable.  A reboot almost always seems to clear it up.  Never saw this issue on earlier versions of -current, so I’m assuming it’s something that crept in.

dmesg report on this device:
iwm0 at pci2 dev 0 function 0: vendor 8086 product 08b2 (rev. 0x83)
iwm0: interrupting at msi2 vec 0
iwm0: hw rev 0x140, fw ver 17.352738.0, address 90:2e:1c:12:36:80

iwm0: fatal firmware error

If anyone has an idea or suggestion to help track this down just let me know and I’ll do what I can to help out.
