I tested but it doesn't fix the problem for me. May be my problem is
different ... as my X60s just doesn't power-off on suspend-to-disk.

My .config says ...
     # CONFIG_CPU_FREQ is not set
     # CONFIG_CPU_IDLE is not set

Also, I've tried CONFIG_DETECT_SOFTLOCKUP=n, but this doesn't fix it either.

Here's the last dmesg after suspend-to-disk and hang there...

CPU 1 is now offline
SMP alternatives: switching to UP code
PM: Syncing filesystems ... done.
Freezing user space processes ... (elapsed 0.00 seconds) done.
Freezing remaining freezable tasks ... (elapsed 0.00 seconds) done.
PM: Shrinking memory...  ^H-^Hdone (0 pages freed)
PM: Freed 0 kbytes in 0.10 seconds (0.00 MB/s)
ACPI: Preparing to enter system sleep state S4
Suspending console(s)

[ ... it just hangs here ... press power-switch does the job, and
system is able to resume upon powering on ]

Thanks,
Jeff.
