Message-ID: <4DC4153E.5020304@suse.com> Date: Fri, 06 May 2011 11:35:26 -0400 From: Jeff Mahoney <jeffm@...e.com> To: Andrew Morton <akpm@...ux-foundation.org> Cc: Ingo Molnar <mingo@...e.hu>, Linux Kernel Mailing List <linux-kernel@...r.kernel.org>, Mandeep Singh Baines <msb@...gle.com> Subject: [PATCH] softlockup: re-increase hung tasks check from 2 minutes to 8 minutes Commit e162b39a, which moved the soft lockup code around a bit, accidentally reverted commit fb822db4, which extended the soft lockup timeout from 2 minutes to 8 minutes. This patch restores it to 8 minutes. From the original patch: >Andrew says: > >> Seems that about 100% of the reports we get of this warning triggering >> are sys_sync, transaction commit, etc. > >increase the timeout. If it still triggers for people, we can kill it.
