I'm seeing this exact problem as well, on the same hardware. The noapic boot option does seem to solve the problem for me, but unfortunately it also makes the mouse pointer very sluggish (I imagine it doesn't get polled often enough by the kernel, or something). The contrast with os X (or, for that matter, linux on the few occasions I do manage to boot it withot noapic) is striking.
I tried attaching a usb mouse, but it has the same problem as the trackpad. -- 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
