Another APIC related function is in the southbridge setup: Hide XIOAPIC PCI function (I think I have it disabled[*]) [*] I had to put this box to production use (even with one CPU visible), but I will have an identical box available in two weeks or so, so I can do more testing then. : I guess that /proc/interrupts shows this system running in PIC mode?

So AFAIK there is no BIOS update available. -Yenya -- | Jan "Yenya" Kasprzak <kas at {fi.muni.cz - work | yenya.net - private}> | | GPG: ID 1024/D3498839 Fingerprint 0D99A7FB206605D7 8B35FCDE05B18A5E | | http://www.fi.muni.cz/~kas/ Journal: http://www.fi.muni.cz/~kas/blog/ | > I will never go to meetings again because I think face to face meetings < > are the biggest waste of time you can ever have. --Linus Torvalds < - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
