...Jens makes a liar out of me, although I read that the 'noht' switch
stops the OS from using H/T but doesn't disable it completely. I make
no warranties regarding the accuracy of this information, though.

Hi Waldo, it really depends on who you ask - Digium say that anything
less than 99.99% is going to result in problems, but ours regularly
runs
at around 99.98% and we don't have any problems.
One of our boxes was running at around 99.96% and we had major issues
with the voice quality packing up from time to time. We disabled
hyper
threading and put the TDM400P on its own IRQ and the results came back
up over 99.98% (haven't had any problems since).
How do you disable hyper threading (what's the command and where is it
placed)?
If this is a Linux box, look at the kernel boot arguments in [lilo|
grub].conf and append "noht", that disables it. My grub.conf on one
of my boxes looks like this:
title CentOS (2.4.21-27.0.4.ELsmp)
root (hd0,0)
kernel /vmlinuz-2.4.21-27.0.4.ELsmp ro root=LABEL=/ noht
initrd /initrd-2.4.21-27.0.4.ELsmp.img
