I was too fast to post previous message after some 10 minutes of
testing. However a recent driver upgrade from 3.13.0-45-generic to
3.13.0-46-generic (with the same firmware) has apparently solved this
issue for me. At least, dmesg does not contain such errors after an hour
of heavy network usage
I am running Ubuntu 14.04.1 LTS and experiencing this issue (broken wifi
until reconnection, Microcode SW error detected. Restarting
0x2000 in dmesg) on Lenovo G550 which has Intel WiMAX/WiFi Link
5150 with the following configuration: broadcast=yes driver=iwlwifi
I am also seeing this with 3.13.0-24-generic.

This bug is present in upstream (3.13 as of rc7) so I don't think it can
be marked fixed.

I have the same problem on the ASUS UX31A (problem is known).
Disabling n-Standard is not really a solution but a very dirty workaround.
This error happens more often if I use Skype.
