Comment 51 for bug 489360

I think I have a similar problem. After upgrading to 10.04 from 9.10 my PS/2 mouse and keyboard would stop working. No Scroll Lock, no Caps Lock, nothing. I could rsh into the machine and do a reboot. I discovered that I could plug in a USB mouse/keyboard and keep working. A co-worker has the same exact HW and we upgraded to 10.04 at the same time, but he says his locks up several times a day even with the USB Mouse/Keyboard.
