Comment 4 for bug 626622

That confirms my suspicion and I agree that the system is severely limited without acpi - but as I indicated, the boot will not proceed if acpi is left on. I suspect that the requirement of booting twice is also a consequence of acpi=off. It looks like the shutdown does not complete and the first boot somehow completes the process. That, of course, is a guess. I have found a number of other bugs with this distribution (no webcam, e.g., which I understand is a consequence of a change in the ia32-libs package). Any suggestions for getting rid of the aicp=off condition, other than waiting for a fix, would be welcome.
