dmesg after booting without noapic an dnolapic
Boots very slowly without noapic and nolapic, presumably from some sort of bug
with ACPI/Bios/Firmware... I have tried this with both mainline and the
Archlinux default kernel, both of which have the same issues, though the Arch
kernel boots a little more quickly without noapic/noalpic.
Lots of these bugs:
[Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored
I fear this is affecting performance, as without apic and lapic dynticks don't
work correctly, to my knowledge.
Attached is a dmesg from booting without noapic and nolapic, a dmesg with
noapic nolapic, as well as the output of lspci and lsusb.
