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 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
in dmesg:

I propose to change the following kernel build options:

CONFIG_MAGIC_SYSRQ_DEFAULT_ENABLE=0x1
Or write
kernel.sysrq = 1

It will enable full SysRq, and the combination
