Message-ID: <4F38C502.40306@gmx.de> Date: Mon, 13 Feb 2012 08:08:34 +0000 From: Florian Tobias Schandinat <FlorianSchandinat@....de> To: LKML <linux-kernel@...r.kernel.org> CC: linux-mm@...ck.org, Jens Axboe <axboe@...nel.dk> Subject: BUG: scheduling while atomic 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.
