 I have nearly the same problem/symptoms on FreeBSD 9.0-STABLE #0 r235121:
 
 siba_bwn0 at pci0:4:0:0:   class=0x028000 card=0x000c1028 chip=0x431514e4
 rev=0x01 hdr=0x00
     vendor     = 'Broadcom Corporation'
     device     = 'BCM4312 802.11b/g LP-PHY'
     class      = network
 
 Toggling hw.bwn.usedma to 0 resulting in less console spam, but the
 operation of the device seems even more flaky then albeit with less console
 spam.
 
 Setting mode 11b also seems to work around the issue, but it's a not really
 a desirable workaround and introduces console spam of "bwn0: unsupported
 rate 0".
