Stress-testing KVM's latest NMI support with kgdbts inside an SMP guest,
I came across spurious unhandled NMIs while running the singlestep test.
Looking closer at the code path each NMI takes when KGDB is enabled, I
noticed that kgdb_nmicallback is called twice per event: One time via
DIE_NMI_IPI notification, the second time on DIE_NMI. Removing the first
invocation cures the unhandled NMIs here.

<title>x86 ACPI: Blacklist two HP machines with buggy BIOSes</title>

<id>e84956f92a846246b09b34f2a728329c386d250f</id>
<content type='text'>
There is a bug in the BIOSes of some HP boxes with AMD Turions which
connects IO-APIC pins with ACPI thermal trip points in such a way that
if the state of the IO-APIC is not as expected by the (buggy) BIOS, the
thermal trip points are set to insanely low values (usually all of them
become 16 degrees Celsius).  As a result, thermal throttling kicks in
and knock the system down to its shoes.

Unfortunately some of the recent IO-APIC changes made the bug show up.
To prevent this from happening, blacklist machines that are known to be
affected (nx6115 and 6715b in this particular case).

This fixes http://bugzilla.kernel.org/show_bug.cgi?id=11516 listed as
a regression from 2.6.26.

On my box it was caused by:

commit 691874fa96d6349a8b60f8ea9c2bae52ece79941
Author: Maciej W. Rozycki &lt;macro@linux-mips.org&gt;

    Signed-off-by: Maciej W. Rozycki &lt;macro@linux-mips.org&gt;
    Signed-off-by: Ingo Molnar &lt;mingo@elte.hu&gt;

and the whole story is described in this (huge) thread:

    http://marc.info/?l=linux-kernel&amp;m=121358440508410&amp;w=4

Matthew Garrett told us about that happening on the nx6125:

    http://marc.info/?l=linux-kernel&amp;m=121396307411930&amp;w=4

and then Maciej analysed the breakage on the basis of a DSDT from the
nx6325:

    http://marc.info/?l=linux-kernel&amp;m=121401068718826&amp;w=4

As far as the Dmitry's and Jason's boxes are concerned, I recognized the
symptoms and asked them to verify that the blacklisting helped.

It appears that the buggy BIOS code has been copy-pasted to the entire
range of machines, for no good reason.
