wpi0 related kernel crashes

[Berndt Josef Wulf <wulf%ping.net.au@localhost>]

G'day,

I'm seeing sporadic kernel crashes since, what I believe, running 
version 4.99.69 and later. The crashes occur when commanding the 
system to reboot or halt from the KDE environment, when it exits 
into the debugger. The following is hand copied and may contain 
errors, but is hoped to reveal enough information to be useful:

uvm_faul(0xc0ae1a80,0xcc95d000,1) -> 0xe
fatal page fault in supervisor mode
trap type 6 code 0 eip c04ae265 cs8 eflags 10292 cr2 cc95d039 ilevel 
0
kernel supervisor trap page fault, code 0
Stopped in pid 150.1 (mount_mfs) at netbsd: VFS_START + 0x25: testb 
$0x1, 0x39 (%ebx)
syncing disk... wpi0: fatal firmware error

System is currently running NetBSD-i386 4.99.72 on a Dell Inspiron 
9400 laptop computer.

dmesg output for the wpi0 device is shown below:

wpi0 at pci3 dev 0 function 0: vendor 0x8086 product 0x4222 (rev. 
0x02)

wpi0: 11g rates: 1Mbps 2Mbps 5.5Mbps 11Mbps 6Mbps 9Mbps 12Mbps 
18Mbps 24Mbps 36Mbps 48Mbps 54Mbps

The system has currently the wpi-firmware2-2.14.4 driver installed.

Has anyone else seen this?
