My device is Compulabs's fitlet. It's a fanless mini PC, also known as mintbox mini.
http://fit-pc.com/wiki/index.php/Fit-PC_Product_Line:_fitlet
Processor's datasheet:
http://support.amd.com/TechDocs/52740_16h_Models_30h-3Fh_BKDG.pdf

The dmesg output:
sp5100_tco: SP5100/SB800 TCO WatchDog Timer Driver v0.05
sp5100_tco: PCI Revision ID: 0x42
sp5100_tco: Using 0xfeb00000 for watchdog MMIO address
sp5100_tco: Last reboot was not triggered by watchdog.
sp5100_tco: initialized (0xffffc90000702000). heartbeat=60 sec (nowayout=0)

Please let me know if you need any other info or tests to be performed.

Denis
