Uh, I see the git fix now. Thanks. The workaround I did was to manually 
offline all CPUs before suspend and that fixed it too.

As for the thinkpad-acpi, here a little patch to disable all hotkeys so 
that Fn-F4 works natively to suspend-to-memory when 
CONFIG_THINKPAD_ACPI_HOTKEY_POLL is not set.

Thanks,
Jeff
