32-bit or 64-bit?

USB Mouse Failure
My desktop machine is running Ubuntu 10.04 (per /etc/lsb-release). Every so often when it boots up, the mouse doesn’t work. The mouse cursor is there, but it won’t move. The most reliable way to fix it is to sudo /sbin/poweroff and restart. sudo /sbin/reboot doesn’t seem to help. This is annoying, as it takes a few restart cycles to come back.
I saw a fix that recommended adding boot options “acpi=force irqpoll” to grub to fix the problem. Ubuntu 10 has grub 2, so I followed the latter set of instructions.
