Edgy Beta (Kernel 2.6.17-10-generic) "acpi=force irqpoll" does not seem to make a difference. I removed "noapic" and rebooted, and I needed to retry five times before it wanted to boot...
But I don't have the reported problems with "noapic" : my mouse speed is normal, and it doesn't miss any key. -- Kernel panic - not syncing: IO-APIC + timer doesn't work! https://launchpad.net/bugs/52553 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
