-//PS+++ fix description
-// Problem is in open high IRQ (acpi.psd /SMP /APIC) at boot time.
-// In my case - this IRQ use SATA and we have flood IRQ. This flood do
-// MASK this IRQ from kernel. Next danis506.add has very slow read from
-// disk.
-// How to fix.
-// At boot time (from DevInit to DevInitComplete) we use low IRQ. In
-// DevInitComplete we close low IRQ and open high IRQ. All values for
-// IRQ we are getting from ACPI call.
