Subject: [Regression] 2.6.24-git3: Major annoyance during suspend/hibernation on x86-64 (bisected)

Hi,

2.6.24-git3 adds a 5 - 10 sec delay to the suspend and hibernation code paths
(probably related to the disabling of nonboot CPUs), which is !@...^&*()
annoying.

It's 100% reproducible on my HP nx6325 and bisection idendified the following
commit as the first bad one:

commit 764a9d6fe4b52995c8aba277e3634385699354f4
Author: Steven Rostedt <srostedt@...hat.com>
Date:   Fri Jan 25 21:08:04 2008 +0100

    sched: track highest prio task queued

Greetings,
Rafael
