Change i8042.c:62 to
#define DEBUG
And see what printk's you get on trying to reboot. i8042_command has a bunch in it that are turned off by default.

Excellent suggestion.

Anything there that says "don't reboot if there is no keyboard"?

Thankyou,

Is that debug output from startup or when you try to reboot the machine?

I just did some further testing, the problem here is exactly the same as Davids. And thinking about the exact point of failure and that Davids reboot problem is related to the keyboard being attached or not I realized what causes the problems for me:

I have a keyboard attached to the PS/2 port, but my mouse is attached to USB. So I pluged in a PS/2 mouse, and guess what? The box rebooted!

Well, this is by no means a solution, but I think it's pretty clear now, what exactly causes the trouble. Now we have to find out, why the i8042 code in 2.6.x breaks things on sertain hardware when there are not devices present in all ports, while in 2.4.x everything went well...

You could also try out the following scenario: remove your USB mouse and _do not_ plug PS/2 one... What you might be seeing is another case of USB Legacy emulation thingy getting in your way.

Just tried it, but I can't see anything special -- keyboard works and the box hangs on reboot, everything as usual...
