Rafael,

dmesg attached. This time, it worked!

I discovered CONFIG_THINKPAD_ACPI caused suspend-to-disk to hang. I
need the Thinkpad ACPI to control the fan and bluetooth. It looks like
the thinkpad acpi is trying acquire locks while suspending. Disabling
cmos, light, led and hotkeys makes suspend-to-disk works again.

Thanks,
Jeff
