Subject: [BUG] igb : rtnl assert on resume
Date: Sat, 08 Oct 2011 19:51:24 +0200	[thread overview]
Message-ID: <1318096284.5276.25.camel@edumazet-laptop> (raw)

Hi guys

Not sure if its a regression (it seems linux-3.0 probably should trigger
same trace) but I caught this on latest net-next when suspend/resume
cycle was done :
