Bug#700629: firmware-iwlwifi: Microcode SW error detected
Package: firmware-iwlwifi
Version: 0.36+wheezy.1
Severity: normal
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi,
I got the following firmware error with my wireless card:
02:00.0 Network controller [0280]: Intel Corporation Centrino Advanced-N
6235 [8086:088e] (rev 24)
However it seems to recover by itself (hence the normal severity) but caused a driver warning.
Note that this error caused absolutely no harm to the connection which remains
stable, looking at statistics in '/sys/class/net/wlan0/' show no errors neither
in the reception nor in the transmission queue.
Sadly I can't find a way to reproduce it easily so debugging it might be
a nightmare!
This bug report might be merged with #550534.
