Hi,

i'm getting this error after i upgraded to xen 3.0.4-1.
It seems, that it doesn't harm anything.

Anyway: for any domU i start, i get this in "xm dmesg":
(XEN) mm.c:566:d1 Non-privileged (1) attempt to map I/O space 000000f0
(XEN) mm.c:566:d2 Non-privileged (2) attempt to map I/O space 000000f0
(XEN) mm.c:566:d3 Non-privileged (3) attempt to map I/O space 000000f0
(XEN) mm.c:566:d4 Non-privileged (4) attempt to map I/O space 000000f0
(XEN) mm.c:566:d5 Non-privileged (5) attempt to map I/O space 000000f0


DomU-kernel ist 2.6.16.33 (xen-sources-2.6.16.33 on gentoo)
(the gentoo package is vanilla kernel + xen patches applied)


Here's complete "xm dmesg":
