kaliber: If I understand correctly, this is a bug also affecting FreeBSD. If so, would you take care of pushing your patch upstream as well?

Replying to luroh:

Yes, I sent a bug report to FreeBSD too.

Forgot to add, that the real problem is in http://dev.haiku-os.org/browser/haiku/trunk/src/add-ons/kernel/drivers/network/wlan/broadcom43xx/dev/bwi/if_bwi_pci.c#L106 - infinity loop, because bwi_devices doesn't have correct sentinel.
