clocksource=jiffies ro console=hvc0
along with /proc/sys/xen/independent_wallclock=1 and running ntpod,
this works fine for hundreds of Debian and Ubuntu VPSes running
2.6.2x Xen kernels.
Andy,
It is still going wrong - 4th reboot - and this time, Dovecot died as
well - at least previously, Dovecot seemed to stay running.

BAD
I had to do a "mknod" for xvda to update grub.
This is what I did :
1) /boot/grub/menu.lst :
Add "clocksource=jiffies" to kopt - run update-grub
Now :
/sys/devices/system/clocksource/clocksource0/current_clocksource
is "jiffies"
2) /etc/sysctl.conf
Add :
xen.independent_wallclock=1
/proc/sys/xen/independent_wallclock is 1
3) Re-enable ntpd
update-rd.d ntp defaults
I confirm all the above is set.
Very strange.
