I'm getting an IRQ 19 Error Nobody Cared.
Google tells me to boot with
irqpoll, but I'm not sure how to do this.
I'm on Ubuntu 8.04.4 LTS.
Assuming you're using Grub Legacy (and not Grub2) :
Search for the relevant menu entry at the end of the file, it looks like that :
Save the file and reboot your computer.
