 (I wasn't sure whether to append to this pr or file my own: My problem
 seems related but is not identical. Anyway, here goes:)
 
 I have an old-ish laptop with the Dell TrueMobile 1180 Internal
 802.11b Mini PCI Card. I get a kernel panic not after kld_load
 bcmwl5_sys.ko, but only after trying to run ifconfig on the interface
 instead:
 
 System: FreeBSD odin 7.0-RELEASE FreeBSD 7.0-RELEASE #0: Sun Feb 24 19:59:52 UTC 2008 root at logan.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC i386
 
 [The system is freshly installed, and bcmwl5_sys.ko is freshly
  generated on the new system.]
 
 First, when running "kldload bcmwl5_sys.ko" I get these messages on
 the console:
 
 ndis0: <Dell TrueMobile 1180 Internal 802.11b Mini PCI Card> mem 0xffc000-0xf8ffdfff irq 9 at device 3.0 on pci2
 ndis0: [ITHREAD]
 ndis0: NDIS API version: 5.0
 ndis0: NDIS ERROR: c000138d (unknown error)
 ndis0: NDIS ERROR: c000138d (unknown error)
 ndis0: using obsoleted if_watchdog interface
 ndis0: Ethernet address: 00:90:4b:b0:07:5b
 
 Next, when I run "ifconfig ndis0 odin ssid foonet mode 11b" I get
 ndis0: NDIS ERROR: c000138d (unknown error)
 ndis0: NDIS ERROR: c000138d (unknown error)
 
 [IIRC, I used to get these under 6.2 as well, so I assume they're
 harmless]
 
 and then the kernel panic.  Output from kgdb below.
