Bug ID: 68591
Summary: Regression: Asrock M3A UCC does not boot without
acpi=off or pci=noacpi
Product: ACPI
Version: 2.5
Kernel Version: 3.12.6
Hardware: x86-64
OS: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: BIOS
Assignee: acpi_b...@kernel-bugs.osdl.org
Reporter: 7egg...@gmx.de
Regression: No

Last tested good kernel: Debian oldstable kernel 2.6.32-5-amd64
Bad kernel: 3.12.6 (needs acpi=off or pci=noacpi)
Also tested bad: Debian stable kernel 3.2.0-4(?).
Also tested bad: Kubuntu 13.10's kernel
Affected board: Asrock M3A UCC
BIOS version: 1.30 and 1.40 (latest)
Error description: The kernel will start to boot, but hang after
"NET: Registered protocol family 1" and before
"ACPI: PCI Interrupt Link [APCF] enabled at IRQ 22" (reached only on 2.6)
My self-compiled kernel (3.12.6) with ACPI debugging seems to indicate an
infinite
loop - it spams plenty of messages too fast to read.
My graphics card seems to crash because of acpi=off/pci=noacpi, so it's not a
solution for me. I'm currently stuck to Debian oldstable ... plusungood.
