Comment 150 for bug 259385

Looks I'm either the first to try i845 user to try Karmic Alpha5, or everyone else is giving up seeing this bug properly repaired.

The good news is that booting with acpi=off allows the boot to complete the desktop. That's progress.

The bad news is that once you're at the desktop, performance is ghastly. top shows xorg sucking back 99% cpu during a screen update, which can take 5-10 just switching focus.

See tarfile for logs etc.
