machine won't reboot

Hi,

I've got an x86 machine that I can't get to reboot in any way, shape or form when it doesn't have a keyboard attached to it. Any suggestions for how to accomplish this?

I've been poking through the kernel sources, and have tried the various reboot= options, but none of them seems to have any effect. The machine just stops and doesn't turn over. Oddly enough, when a keyboard is attached, things seem to go ok (must be due to the mach_reboot call using the... *keyboard* of all things?!).

Thankyou, Dave

Is this a PC ? Does it hang before the linux loader is started ?

Here you often have a BIOS option for this. Some PCs can't start without the keyboard at all.

This is why some keyboard/monitor switches have a simulated keyboard for each PC.

No, it doesn't reboot at all. It doesn't get to the BIOS or anything like that. It gets to the mach_reboot code in the kernel and just stops.

That I would have understood, I've seen that before. This just seems to hang/halt the computer without rebooting it.

Thanks, Dave

Some old AT based machines do that. They didn't fully support the ATX reboot/shutdown methods so they would just hang on restarts.
