John Baldwin f203f177f4 Revert part of the "BIOS brain damage" from rev 1.10. It seems that ... different BIOSs use the same exact settings to mean two very different and incompatible things for the SCI. Thus, if the SCI is remapped to a PCI interrupt, we now trust the trigger/polarity that the MADT provides by default. However, the SCI can be forced to level/lo as 1.10 did by setting the tunable "hw.acpi.force_sci_lo" to a non-zero value from the loader. Thus, if rev 1.10 caused an interrupt storm, it should nwo fix your machine. If rev 1.10 fixed an interrupt storm on your machine, you probably need to set the aforementioned tunable in /boot/loader.conf to prevent the interrupt storm. The more general problem of getting the SCI's trigger/polarity programmed "correctly" (for some value of correctly meaning several workarounds for broken BIOSs and inconsistent "implementations" of the ACPI standard) is going to require more work, but this band-aid should improve the current situation somewhat.
