Subject: [x86] Kernel panic - not syncing: Fatal exception in interrupt
Greetings,
I got the below dmesg and the first bad commit is
commit 51b2c07b22261f19188d9a9071943d60a067481c
Author: Jiri Kosina <jkosina@...e.cz>
Date: Fri Jul 12 11:22:09 2013 +0200
x86: Make jump_label use int3-based patching
Make jump labels use text_poke_bp() for text patching instead of
text_poke_smp(), avoiding the need for stop_machine().
