Re: [Xen-devel] illegal page update with latest xen-unstable

Yup.  I was surprised, it'd been running pretty well with the 1.0, but a lot
of what I'm interested in requires the vbd stuff.

Done, no change, unfortunately.  For what it's worth I'm using libc 2.3.1
and gcc 3.2.2, from the slack 9.0 builds, in domain 0.

Ok, the only new output that generated was:

DOM0: (file=memory.c, line=504) Bad page type/count (06000000!=07000000) cnt=1  
DOM0 FATAL ERROR: Illegal page update request  

Hope that helps track it down, if I have time I'll poke in the source too but
am just doing this as a hobby alongside work at the moment.

I can include complete boot logs if it'll help, but didn't want to flood them
if it wasn't going to be useful.
