Hi Andrew,
If you wish to try this before they install their KVM units. You could set
your grub configuration file to have a fallback option.
In detail, this basically means if it kernel panic's, it will boot with a
working kernel option. So you could have one with the parameter
"no_timer_check=0" and another one with the default kernel parameter you had
before you edited.
So in therapy, it should return from a failure without having to be in front
of the server.
Example
---
##START OF GRUB CONFIG##
#standard settings.
default=0
timeout=0
# Fallback to the Third entry, if the first one fails.
fallback 2
#kernel options
title Kernel With No Timer Check and APIC (2.6.13smp)
root (hd0,0)
kernel /vmlinuz-2.6.13smp ro root=/dev/VolGroup00/LogVol00
no_timer_check=0 acpi=noirq noapic
initrd /initrd-2.6.13smp.img
title Kernel With No Timer Check Zeroed (2.6.13smp)
root (hd0,0)
kernel /vmlinuz-2.6.13smp ro root=/dev/VolGroup00/LogVol00
no_timer_check=0
initrd /initrd-2.6.13smp.img
title Working Kernel(2.6.13smp)
root (hd0,0)
kernel /vmlinuz-2.6.13smp ro root=/dev/VolGroup00/LogVol00
initrd /initrd-2.6.13smp.img
##END OF GRUB CONFIG##
Hope this gives you another option. :-)

Hi Karl,
Thanks. Unfortunately I don't think their techs like messing with
customer equipment beyond reboot requests. They're phasing in a KVM-
over-IP service next week, but that's not a lot of use to me r.n. :-)
I'll remove all of it and try your suggestion below when the virtual
KVMs up and running. Thanks again!
Cheers
Andrew
