Subject: BUG: scheduling while atomic
Date: Mon, 13 Feb 2012 08:08:34 +0000 [thread overview]
Message-ID: <4F38C502.40306@gmx.de> (raw)
Hi all,
since I upgraded to 3.3-rc3 I received this bug. Probably a regression although
I also recently updated git, so I can't say for sure. It looks like it happens
quite often here when doing git push in kernel trees.
