Description (last modified by kallisti5)

Booting latest hrev43091 gcc4 image results in multiple problems on an Asus M5A97 EVO UEFI mainboard.

last log message seen before lockup:

ACPI Error: [RAMB] Namespace lookup failure, AE_NOT_FOUND
.
.
usb ohci -1: smm is in control of the host controller

This board doesn't have a serial port built-in so logs will be difficult given the lock up is so early.

Disabling APIC and ACPI gives a continuous loop of...

ahci: AHCIPort::InterruptErrorHandler port 0, fCommandsActive 0x00000000, is 0x00000040, ci 0x00000000
ahci: ssts 0x00000001
ahci: sctl 0x00000301
ahci: serr 0x40800000
ahci: sact 0x00000000
ahci: Port Connect Change
