Hi,

Sorry for the delayed reply.

I was running dom0 kernel download from mercurial repository when "make
world". The version is 2.6.18.8-xen. And I used the default kernel config.

I cannot post the dmesg now as I am on a trip. If that's critical for the
diagnosis, I will post them asap. Thanks!

-Fred
