I think this issue is somehow related to interrupt sharing. I have Nvidia 8600M graphic card and my problem with Microcode errors and networking restart started, when i've added the line "options nvidia NVreg_EnableMSI=1" to /etc/modprobe.d/options.conf
After disabling this option I have no more "iwlagn 000:0c:00.0: Microcode SW error detected. Restarting 0x92000000" messages. -- iwl4965: Microcode SW error detected.
