We've had about 20 reports of this bug in the last 2 days. No idea why it only just started showing up, but it may coincide with users updating from 3.4->3.5 when we pushed an update.

Seems to be affecting multiple different network drivers. (The original trace is a 'crap' driver from staging, but there are
reports from e1000e and iwlwifi for eg)

Could this be related to the "recvmsg bug" WARN's we've also been seeing recently ?
