Experiencing the same oopses, every now and then, with both kernels 3.8 and 3.9. Wireless traffic only in bursts: traffic coming through for a couple of seconds, and then stalling for seconds, cycling.
Description of problem: Resumed from suspend. When prompted for password to WiFi network, entered credentials and connected. Started to use web browser, then received the abrt alert about this error. I think this is the actual problem, preceding the stack trace: ------------------------------------------------------------------------- Jun 17 13:05:45 eval-dell-xps-l322x kernel: [ 9261.213720] iwlwifi 0000:01:00.0: Microcode SW error detected.
