[SOLVED] Suspend fails with Maxtor external drive plugged in

Here is a problem I just solved; I'm documenting it here in case anyone else runs into this.

Suspend was failing sometimes on my Thinkpad X301 running 3.3.5-1-ARCH. The little moon would blink indefinitely, there was no way to escape it other than a hard reboot. I eventually realized it was happening only when my Maxtor external drive was plugged in. It turns out the module causing the problem is ums_onetouch, which controls the "one touch" backup button, something I never use anyway. I fixed the problem by creating:

/etc/pm/config.d/modules

with the line:

SUSPEND_MODULES="ums_onetouch"

This unloads the culprit module before suspending. Now it suspends fine.
