[Xen-devel] Stop the continuous flood of (XEN) traps.c:2432:d0 Domain attempted WRMSR ..

[Pasi Kärkkäinen <pasik@xxxxxx>]

Hello,

IIRC there was some discussion earlier about these messages in Xen's dmesg:

(XEN) traps.c:2432:d0 Domain attempted WRMSR 00000000000001ac from 
0x0000000000c800c8 to 0x0000000080c880c8.
(XEN) traps.c:2432:d0 Domain attempted WRMSR 00000000000001ac from 
0x0000000000c800c8 to 0x0000000080c880c8.
(XEN) traps.c:2432:d0 Domain attempted WRMSR 00000000000001ac from 
0x0000000000c800c8 to 0x0000000080c880c8.
(XEN) traps.c:2432:d0 Domain attempted WRMSR 00000000000001ac from 
0x0000000000c800c8 to 0x0000000080c880c8.

At least on my systems there's continuous flood of those messages, so they will 
fill up the
Xen dmesg log buffer and "xm dmesg" or "xl dmesg" won't show any valuable 
information, just those messages.

I seem to be getting those messages even when there's only dom0 running.
Is the plan to drop those messages? What's causing them? 

hmm, according to this bugzilla 
https://bugzilla.redhat.com/show_bug.cgi?id=470035,
they're related to dom0 kernel acpi-cpufreq ?

Also it seems there was discussion about the subject on 2011/08:
http://old-list-archives.xen.org/archives/html/xen-devel/2011-08/msg00561.html


Xen hypervisor 4.1.2.
dom0 Linux kernel 3.2.2.


Thanks,

-- Pasi
