Subject: Re: kern/116747: [ndis] FreeBSD 7.0-CURRENT crash with Dell
TrueMobile 1400 wireless card

(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@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.
# kgdb /boot/kernel/kernel /var/crash/vmcore.1
