I have discovered that Windows XP and Windows 7 both successfully signal the pc to reboot when the reboot option is selected in Windows.

But under Linux - Ubuntu through 9.04, and CentOS through 5.3, even with a recent BIOS upgrade, the PC hangs when Linux says it is rebooting. I need to manually press the power switch to shut down the system.

I have yet to try with any of the *BSD family.

Thoughts? Inisghts?

Thanks.

4) And eventually :

5) Wait for the fit-pc2 to shutdown.
6) Press the power switch on. You're now able to reboot.
