Re: Call for Test and Review: bwn(4) - another Broadcom Wireless driver

Hi,

Thanks for the work !

I have some problems here when I try to create a wlan interface :
bwn_v4_ucode5: could not load firmware image, error 2
bwn0: the fw file(bwn_v4_ucode5) not found

I have installed bwn-firmware-kmod from ports but the only files I have in
/boot/modules are bwn_v4_lp_ucode.ko and bwn_v4_ucode.ko. So I tried to
copy bwn_v4_ucode to bwn_v4_ucode5 and it seems to work : wlan0 is
created, I can associate to an open Access Point and obtain a DHCP lease.
But if I try to do some network IO (browsing the web) the interface hang
(I cannot obtain a lease anymore).

I'm running :
FreeBSD acheron.homeunix.org 9.0-CURRENT FreeBSD 9.0-CURRENT #3 r204476M:
Sun Feb 28 20:27:03 CET 2010
miki_at_acheron.homeunix.org:/usr/obj/usr/src/sys/ACHERON  amd64

kernel and world are in sync.
