Ok, that helps for the nvidia chipset, too. The mainboard is a Gigabyte
nforce4ultra (GA-K8NF9 Ultra).

On the first try, it worked fine with the non-SMP kernel, without adding any
extra kernel options:

Bootdata ok (command line is root=/dev/sda2 ro console=tty0 )
Linux version 2.6.15-1-amd64-k8 (Debian 2.6.15-4) 

Afterwards, neither the SMP nor the non-SMP of 2.6.15 wanted to boot... now I
am back to 2.6.12-smp.

Summary:
2.6.12-1-amd64-k8-smp with disable_timer_pin_1: clock ok
2.6.12-1-amd64-k8-smp without "               : clock too fast

2.6.15-1-amd64-k8-smp: does not boot
2.6.15-1-amd64-k8: ok once, does not boot after that

Are there know problems with 2.6.15? We lost the home partition on am AMD64
machine on saturday morning, where home is on lvm over raid. Friday
afternoon I had upgraded the machine to 2.6.15-1-amd64-k8, saturday morning,
without anybody working on the box, is started to give ext3 errors. Now I am
supposed to fix this, and it does not look good...
