Hi Al,
In the e-mail archives I've seen the following message:
http://ivtvdriver.org/pipermail/ivtv-users/2010-January/009760.html
"
I also had this problem with an old VIA board. Rebooted under heavy
load, as in, when more than one tuner started recording.
The following append fixed it, and it ran for years:
append="noapic nolapic pci=noacpi acpi=off"
"

I have altered my /boot/grub/menu.lst:
old:
title Ubuntu 9.04, kernel 2.6.28-17-generic
uuid c4888a22-cd4e-4d34-b5c2-a17b4aafb8e2
kernel /boot/vmlinuz-2.6.28-17-generic root=UUID=c4888a22-cd4e-4d34-b5c2-a17b4aafb8e2
ro quiet splash
initrd /boot/initrd.img-2.6.28-17-generic
quiet

new:
title Ubuntu 9.04, kernel 2.6.28-17-generic PVR500-fix
uuid c4888a22-cd4e-4d34-b5c2-a17b4aafb8e2
kernel /boot/vmlinuz-2.6.28-17-generic root=UUID=c4888a22-cd4e-4d34-b5c2-a17b4aafb8e2
ro noapic nolapic pci=noacpi acpi=off
initrd /boot/initrd.img-2.6.28-17-generic
quiet

My system still reboots a few seconds after I press "watch TV" on mythTV.
Directly after pressing return I hear the Hdd rattle for a few seconds, then
I see the BIOS screen

dmesg is attached.

Regards,
Cedric
