Been having this problem for years on my Shuttle SN78SH7 too (this model has a nVidia GeForce 8200 chipset). In my setup just adding "noapic" to the kernel boot option solves the problem.
BTW, I'm running Fedora 15 with kernel 2.6.42.3-2.fc15.x86_64, so this is not Ubuntu specific. Also, I'm managing thee Ubuntu PCs at work, so I guess this entitles me to post here too;-) ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/627862 Title: USB Mouse freezes randomly but consistently To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/627862/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
