16:10 < mischief> i wonder why enabling *acpi= makes reads take so long
16:11 < cinap_lenrek> wrong interrupts
16:11 < mischief> huh?
16:12 < cinap_lenrek> the difference between *acpi= and *acpi=0 is that with
*acpi= we use acpi to extract the pci irq to apic mapping
16:13 < cinap_lenrek> with *acpi=0, we just expose the acpi tables to userspace
