I have an HP pavilion zd825us which has a Broadcom ethernet that appears to be 
supported by the new bwn driver. I have, for several years now, been using the 
NDIS driver based on Project Evil. Since bwn came out in 8.1, I tried it and 
it pretty much works but I get a couple errors sporadically.  Here are the 
dmesgs:
Aug 21 11:39:29 laptop2 kernel: siba_bwn0: <Broadcom BCM4318 802.11b/g 
Wireless> mem 0xc8206000-0xc8207fff irq 17 at device 3.0 on pci11
Aug 21 11:39:29 laptop2 kernel: bwn0 on siba_bwn0

type 2 rev 7) RADIO (manuf 0x17f ver 0x2050 rev 8)

Aug 21 11:39:29 laptop2 kernel: bwn0: [FILTER]
Aug 21 11:39:29 laptop2 kernel: bwn0: firmware version (rev 410 patch 2160 
date 0x751a time 0x7c0a)

Aug 20 17:01:37 laptop2 kernel: bwn0: RX decryption attempted (old 0 keyidx 
0x2)

Occasionally, a message appears  on the console indicating that mDNSResponder 
had an issue:
Aug 20 19:45:42 laptop2 mDNSResponder: mDNSPlatformSendUDP got error 51 
(Network is unreachable) sending packet to 224.0.0.251 on interface 
127.0.0.1/lo0/2


Aug 21 11:39:56 laptop2 mDNSResponder: mDNSResponder (Engineering Build) (Aug  
4 2010 09:50:01) starting

And when I use the NDIS driver, I see this lock not held...
Aug 21 11:39:56 laptop2 mDNSResponder: mDNS_AddDNSServer: Lock not held! 
mDNS_busy (0) mDNS_reentrancy (0)
