I have encounted this problem too. I've learned that disabling
ichlpcib* allows to shutdown cleanly. 

Fragments from dmesg:

ichlpcib0 at pci0 dev 31 function 0
ichlpcib0: vendor 0x8086 product 0x24cc (rev. 0x01)
timecounter: Timecounter "ichlpcib0" frequency 3579545 Hz quality 1000
ichlpcib0: 24-bit timer
ichlpcib0: TCO (watchdog) timer configured.
ichlpcib0: SpeedStep enabled

But Celeron-M used in my Thinkpad doesn't have SpeedStep.

I've filed PR for this.
