These all work fine. Which acpi functions depend on apic? How will > acpi missbehave if apic is not installed. Any remedies? > Since the apic maps the interrupts, and acpi monitors the interrupts for activity, a broken apic implementation can prevent acpi from working properly. I know on my machine (which is a desktop) if I boot with apic off but acpi on, I get an entry about avery .1 second about apic errors in my message log that I presume are coming from acpi, because if I then boot with acpi=off in addition to noapic the errors go away.
It seems that acpi for laptops is much more advanced than it is in the desktop arena, so you're laptop may work fine, but many desktops get hosed. - -- Greg -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.7 (GNU/Linux) iD8DBQE+VBkOGu5uuMFlL5MRAnJpAJ0etfxiE6/VqoHin3F/Ea5lZhN6nACfcn1w toBDxPQc7wj84SbGk8hLle4= =KiDS -----END PGP SIGNATURE-----
