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,

Package: linux-source-2.6.18
Version: 2.6.18.dfsg.1-11
Severity: important
Hello,
I have recently dist-upgraded my workstation from Sarge to Etch. As usual,
this operation worked fine, but sadly I get some trouble with the 2.6.18
kernel included into Etch.
To begin, I have tried the linux-image-2.6.18-4-k7 but at the first boot
the kernel freeze completely (the MagicSysReq keys doesn't work). So I
build my own image from the current linux-source-2.6.18 to test if the
problem could be eventualy solved with more specific options related to
my hardware configuration.
After rebooting without problem on my own linux-image kernel, for a moment
all seemed to work fine... until the whole system freeze again during the
configuration process of some new packages I have planned to install.
Despite the log files contains nothing useful, investigating a bit (eg.
more reboots and freezes later :-D show that the problem always occurs
during disk i/o operations, specially when loading the system at boot or
installing/deinstalling packages (heavy disk usage = faster freeze).
Of course, I did not have any problem when I use my previous kernel as
fallback (an old 2.6.8 version build with the Debian Sarge sources).
Perhaps a disk driver (I use the AIC7XXX kernel module) bug ?
