Subject: BUG: scheduling while atomic: ifup-bonding/3711/0x00000002 -- V3.6.7
Date: Tue, 27 Nov 2012 12:37:30 -0800 [thread overview]
Message-ID: <50B5248A.5010908@tlinx.org> (raw)
Is this a known problem / bug, or should I file a bug on it?
It doesn't cause a complete failure, and it happens multiple times (~28
times
in 2.5 days?... so maybe 10x/day?) about 8 start with ifup, and the rest
start @ kworker -- both happen upon enabling the bonding driver
on a 10Gb dual port adapter (trying to get 1 20Gb adapter).
The 2 tracebacks tyeps (ifup-bonding + kworker) follow:
