My solution on gentoo:
http://forums.gentoo.org/viewtopic-p-7018250.html
[root@myhost ~]# find /lib/modules -iname '*ehci*'
/lib/modules/3.3.2-1-ARCH/kernel/drivers/usb/host/ehci-hcd.ko.gz
Also, there is no need to blacklist. Just remove the module in /etc/rc.local.shutdown.
]]>The issue is not solved for me. I blacklisted e1000e, upgraded kernel to 3.3.2, and do not run laptop-mode. I started new topic on gentoo forums:

How would you track down the issue?
]]>I'll remember to fire up google next time I need to search the arch forums.
You may consider this => https://startpage.com/ <= a safe Google replacement. It works as expected.
]]>Marked as fixed. I followed the instructions and disabled laptop-mode runtime power management, in /etc/laptop-mode/conf.d/runtime-pm.conf:
# Control Runtime Power Management ?
CONTROL_RUNTIME_PM=0
# Enable debug mode for this module
# Set to 1 if you want to debug this module
DEBUG=0
I keep missing the relevant topics when I search the forums, what keywords did you search for to find this topic ?
]]>I'm running an up to date arch 64, KDE on a thinkpad x220. Recent changes includes a kernel upgrade, a grub2 upgrade and the addition of multilib and installation of a many libs from multilib (these libs are no longer needed).
It's probably unrelated but I should mention that I had previous issues with my thinkpad not powering down related to a e1000e bug. Fixed by removing the e1000e module in rc.local.shutdown.
Any idea where to start looking for clues ?
-edit-
I forgot to mention that "POWER OFF" is printed on screen, then it seems to shut down for a couple seconds before it reboots, it's not an instant reboot.
