2.6.12.3 clock drifting twice too fast (amd64)

[jerome lacoste <jerome.lacoste@gmail.com>]

Installed stock 2.6.12.3 on a brand new amd64 box with an Asus extreme
AX 300 SE/t mainboard.

I remember seeing a message in the boot saying something along:

  "cannot connect to hardware clock."

And now I see that the time is changing too fast (about 2 seconds each second).

I don't have visual on the boot sequence anymore (only remote access).
Kernel earlier than 2.6.11 won't boot on the box (SATA chipset unsupported).

Some info below (probably irrelevant).

What should I try?
