In your boot options, you need to add: acpi=off Look in /boot/grub/menu.lst put it before "ro" in the linux entries.
OR, do it manually from the grub menu the first time to see if it fixes the problem. Apparently the rt2500 driver truly hates whatever the kernel is doing for acpi. It's not a *good* solution, but it sure seems to fix things for me. -- events/0 uses all of cpu, causes big slowdown https://bugs.launchpad.net/bugs/67126 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
