Hello all,
I've done as Alexander has suggested:
added a boot option in /boot/grub/menu.lst
----snip---->
title Debian GNU/Linux, kernel 2.6.18-4-k7
root (hd0,0)
kernel /vmlinuz-2.6.18-4-k7 root=/dev/sda2 ro clocksource=tsc
initrd /initrd.img-2.6.18-4-k7
savedefault
rebooted and:
># echo "tsc" >
/sys/devices/system/clocksource/clocksource0/current_clocksource <
># cat /sys/devices/system/clocksource/clocksource0/* <
jiffies tsc pit
tsc
We are up and running now (45min.). Alex. has been up for some hours
(9+) using this method. So maybe others can use this and help us
understand later the "why" of it.
Anyway, fingers crossed let us see........

Hello Steve,
uptime with "nosmp" so far: 57 min. Everything runs fine and
smoothly. Of course overall system load is about 5 percent (average)
to 20 percent (peak) higher than usual - man, i do love and miss smp.. :D
Just kidding, i can easily live happily either with "nosmp" or
particularly with 2.6.17 for now. Maybe other affected users might
agree to lower the initial severity to "important"?
But guess who appears on stage now again (dmesg log):
#Time: pit clocksource has been installed.
#...
#Real Time Clock Driver v1.12ac
#Generic RTC Driver v1.07
RTC is back for good!
This makes me so curios about the mysticals of linux time again:
http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=734efb467b31e56c2f9430590a9aa867ecf3eea1
After reading, re-reading and hopefully understanding i will try to
find a solution, why 2.6.18-k7 decides to use "Programmable Interval
Timer" of 1981(!) instead of our even younger and trusted friend "rtc"
or even the fancy "acpi_pm" ..
Once i find helpful information or even a solution, i will post it here.
Thank you very much again!

Sure, it could be, but I don't know anything about the architecture
of the
kernel's clocksource stuff.
Good luck,
--Steve Langasek Give me a lever long enough and a
Free OS
Debian Developer to set it on, and I can move the
world.
