Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master
commit e164ade07b215cc33da6831734140f0aa0615d0a
Author: Chris Metcalf <cmetcalf@xxxxxxxxxx>
AuthorDate: Thu Apr 2 13:25:32 2015 -0400
Commit: Chris Metcalf <cmetcalf@xxxxxxxxxx>
CommitDate: Mon Apr 6 12:35:02 2015 -0400
watchdog: add watchdog_exclude sysctl to assist nohz
Change the default behavior of watchdog so it only runs on the
housekeeping cores when nohz_full is enabled at build and boot time.
Allow modifying the set of cores the watchdog is currently running
on with a new kernel.watchdog_exclude sysctl.
