I got 2.6.18-rc4-mm1 going, and it appears that system
moves at about 3x normal speed. A software clock need 3
seconds to advance 10 seconds, for example.

Everything else seems faster too, the keyboard autorepeat,
delay loops in games, and so on.

Guess I could live with this, if it'd also compile
3x faster. :-/

This is a x86-64 kernel, with the jiffies hotfix applied.
Sounds like the same issue Gregorie Favre is dealing with.

Please send full dmesg output.

Does 2.6.18-rc4, or 2.6.18-rc3-mm2 have this issue

FWIW i looked through the x86-64 patch changes between
rc3-mm2 and rc4-mm1 and I can't find anything that would be remotely
related to the timer.

If it's confirmed to have regressed in this time it would require a binary search to track down I think.
I have narrowed it down. 2.6.18-rc4 does not have the 3x time
problem, while mm1 have it. mm1 without the hotfix jiffies
patch is just as bad.
