It's too vague to know. The error comes from lapic_handle_error(), which is a generic/small routine which pulls the local APIC error status register. (Note I'm saying APIC, not ACPI -- two different things) apic_vector.S sets this up/makes use of this function, and its done as an interrupt handler. I think this is one of those situations where you have to know *what* is being set up/done at that moment in time for the error code to mean something. Maybe booting verbose would give more information as to what was being done that lead up to the line. I've CC'd John Baldwin who might have some ideas. -- | Jeremy Chadwick jdc@koitsu.org | | UNIX Systems Administrator http://jdc.koitsu.org/ | | Making life hard for others since 1977. PGP 4BD6C0CB |
