[Xen-devel] d0 Error pfn 100

["Christoph Egger" <Christoph.Egger@xxxxxxx>]

Hi!

I see these messages from the xen-kernel:

(XEN) /usr/src/xen-unstable.hg/xen/include/asm/mm.h:186:d0 Error pfn 100: 
rd=ffff8300df05c100, od=0000000000000000, caf=00000000, taf=0000000000000000
(XEN) mm.c:636:d0 Error getting mfn 100 (pfn 5555555555555555) from L1 entry 
8000000000100125 for dom32753
(XEN) /usr/src/xen-unstable.hg/xen/include/asm/mm.h:186:d0 Error pfn 100:

Xen does not crash, Dom0 continues to run.

System configuration:

x86_64 debug xen-kernel, x86_64 linux-2.6.18 dom0 kernel built from xen tree,
OpenSuSE 10.2 distribution as Dom0.

Steps to reproduce:

Launch yast, select "Network devices" and "Network card".
yast now reads config entries. If you are on a serial console where screen 
refreshes are slow enough, you should see that xen prints something.
Exit yast without changing anything. Back on command line run "xm dmesg".
There you can see the above xen messages.

This is repeatable. Doing this multiple times without reboot, you can always 
see the same message even with the same numbers.


Question:

Can anyone else on this list reproduce this?
