From 664dfa65e84429d0b68694483e1de7365c7c56fb Mon Sep 17 00:00:00 2001 From: Dave Jones Date: Thu, 22 Dec 2011 16:39:30 -0500 Subject: [PATCH] sched: Disable scheduler warnings during oopses The panic-on-framebuffer code seems to cause a schedule to occur during an oops. This causes a bunch of extra spew as can be seen in: https://bugzilla.redhat.com/attachment.cgi?id=549230 Don't do scheduler debug checks when we are oopsing already.
