[Bug 565202] Re: BUG: soft lockup - CPU#0 stuck for 74s! [ksoftirqd/0:4]

[Tony Mugan]

The actual settings required in BIOS (M2v-MX Motherboard BIOS v1005
09/14/07) are as follows to avoid CPU soft lockups...

Under the "Power" menu

ACPI 2.0 Support [YES]
ACPI APIC Support [Disabled]

And the lockups go away :)

Have just confirmed with latest available mainline kernel
(http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.34-rc6-lucid/)  that
the lockups will still happen if APIC support is enabled in BIOS

tony at orac:~$ uname -r
2.6.34-020634rc6-generic
