Date: Sat, 25 Nov 2006 11:48:44 -0800 From: Don Mullis <dwm@...r.net> To: Andrew Morton <akpm@...l.org> Cc: linux-kernel@...r.kernel.org, mingo@...e.hu Subject: Re: 2.6.19-rc6-mm1 -- sched-improve-migration-accuracy.patch slows boot > +sched-improve-migration-accuracy.patch > +sched-improve-migration-accuracy-tidy.patch Bisection shows that this pair of patches raises the boot time; specifically, the delay from logging of "INIT: version 2.86 booting" to " Welcome to Fedora Core" goes from 4s to 4m40s. From there to "Setting clock (utc): Sat Nov 25 10:18:11 PST 2006 [ OK ]" takes an additional 30s. A possibly relevant observation: On this particular box, `date` is always a few seconds behind `hwclock`. The time difference varies from boot to boot, but does not appear to grow over time.
