Perhaps nobody still has this problem. More likely, anybody with this problem may well have given up on Linux.
I still do have the problems and believe me, I'll trash this piece of crap they call a laptop before giving up on Linux :)
If you have a problem like this (clock running at double speed), but your notebook is based on the ATI chipset, perhaps you should look at http://bugme.osdl.org/show_bug.cgi?id=3927 Do either of these ring a bell with anyone?
Ok, what doesn't show in the bug 3341 is that I kept digging with Andy Kleen and Andy came up with an implementation that doesn't use the PIT at all, just using the ACPI timer.
You need to run a 2.6.16 Linux kernel and pass the options "apicpmtimer" at boot time. It works well, but we hit another bug, in that there is no ticking at all on these buggy laptops if you stop the PIT timer. The systems seems to hang until the user generates an event (by pressing a key for example). You can boot the system safely by keeping a key pressed (like shift for example). Not very handy, but it's a good improvement over the previous problems with timer.
If you are using an older version of the kernel (2.6.12 to 2.6.15); you may also want try one of my patches listed here:
