While upgrading, I found out that my Asrock M3A UCC mainboard is no longer compatible with current Linux' acpi. The BIOS version was 1.30, now I upgraded to 1.40 (latest) without a change. (Error description below) I found no other information from other people using the same mainboard suffering from or solving this bug. What's the best way to find (and fix) the cause? Debugging using self-compiled kernels (with enabled debugging)? Bisecting? Asking somewhere else? 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 with ACPI debugging seems to indicate an infinite loop - it spams plenty of messages too fast to read. Debian oldstable kernel 2.6.32-5-amd64 works fine. Debian stable kernel 3.2.0-4(?) needs acpi=off or pci=noacpi. Same with Kubuntu 13.10's kernel. Same with self-compiled kernel 3.12.6. With acpi=off or pci=noacpi, the nvidia X11 driver crashes ... but that's a different story. with kind regards Bodo Eggert -- Achtung Outlook-Fehler: Sollte diese Mail nicht korrekt dargestellt werden, so hat Microsoft mal wieder die "unnötigen" Zeilenumbrüche ausgeblendet.
