Bug#252289: weird clock

["Martín Ferrari" <martin.ferrari@gmail.com>]

Hi!

I want to report that I'm having a very similar problem since some
months ago. It is a woody install, with 2.4.18 stock debian kernel. It
doesn´t freeze, but the clock derives very quickly from real time. I
have just checked the timer interrupt, and it seems that it's ticking
at 99Hz. The computer has a PS/2 KVM-switch plugged (it emulates a
real keyboard). Any recommendation?
