In doing a web search on system clock speeds being too high, I found entries describing exactly what I am experiencing in the linux-kernel list archives, but have not yet found a resolution.

I have Mandrake 10.0, kernel-2.6.3-7mdk installed, on an IBM Thinkpad 1412 laptop, celeron 366, 512MB RAM. I am finding that my system clock is ticking away at a rate of about 3:1 vs reality, ie, I count ~3 seconds on the system clock for every 1 real second. I am running ntpd but this is unable to keep up with the rate of system clock passage.

I had to slow my keyboard repeat rate _way_ down in order to be able to type at all as well. The system is limited, in that I have no way to alter the actual system clock (in bios at any rate). The CPU is properly identified as a celeron 366.

Does anyone have any enlightenment, or a fix, to offer? The exact same software setup on a desktop system, Athlon XP2700+, has no such problems.

Try this in the boot command line "clock=pmtmr". If that fails, then try "clock=pit".
