Hello,

please help with this issue, the error message is cryptic I don't know 
what error -2 means:

b43 bcma0:1: Direct firmware load for b43/ucode30_mimo.fw failed with 
error -2
b43 bcma0:1: Direct firmware load for b43/ucode30_mimo.fw failed with 
error -2
b43 bcma0:1: Direct firmware load for b43-open/ucode30_mimo.fw failed 
with error -2
b43 bcma0:1: Direct firmware load for b43-open/ucode30_mimo.fw failed 
with error -2
b43-phy0 ERROR: Firmware file "b43/ucode30_mimo.fw" not found
b43-phy0 ERROR: Firmware file "b43-open/ucode30_mimo.fw" not found
b43-phy0 ERROR: You must go to 
http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware and 
download the correct firmware for this driver version. Please carefully 
read all instructions on this website.

Yet, ls -al /lib/firmware/b43/ucode30_mimo.fw:

-rw-r--r-- 1 root root 39632 Apr  6 18:09 /lib/firmware/b43/ucode30_mimo.fw

it's there, as put by b43-fwcutter package (Debian 1:019-2). Though I 
don't have b43-open directory, tried symlinking it, didn't help.

The kernel is virgin 4.2.0 Linus, custom compiled, relevant config 
entries below, am I missing something?

CONFIG_B43=y
CONFIG_B43_BCMA=y
# CONFIG_B43_BUSES_BCMA_AND_SSB is not set
