I get screenfulls of this message when trying to boot xenU:
Timer ISR: Time went backwards: -472618592
Timer ISR: Time went backwards: -471563592
Timer ISR: Time went backwards: -470508592
Timer ISR: Time went backwards: -469454592
Timer ISR: Time went backwards: -468375592
Timer ISR: Time went backwards: -467313592
Timer ISR: Time went backwards: -466252592
xen0 works fine.
it also doesn't appear to boot but with all those messages it's hard to tell why.

There have been some pretty significant checkins to the unstable
tree today:

First off, we've made it so that by default 'make world' builds a
Linux kernel rather than 2.4.27. I know a lot of people
still use 2.4, but I think its important the 2.0 release is
"2.6 native".

Secondly, a number of important MMU optimisations have just been
enabled in the tree. Performance should now be as good as
2.4. We've done a fair bit of testing, but should you have
problems, it would be useful to know if you can repeat with
CONFIG_WRITABLE_PAGETABLES disabled in the linux kernel.

I've created a new xen-2.0.bk tree on xen.bkbits.net which is
where the source for the 2.0 release will live. For the next few
weeks we expect this tree to simply be a time-lagged version of
the xeno-unstable.bk tree: bug fixes will get road tested in the
unstable tree then pushed to 2.0 if no problems are reported.

To clone the proto 2.0 tree use "bk clone bk://xen.bkbits.net/xen-2.0.bk"

NB: We've named the repository 'xen' rather than 'xeno' as the
latter name no longer makes sense now that the XenoServer project
now lives in a different repository. 

We'd be grateful if as many people as possible could test this
beta over the next few days, so we can shake out any bugs before
the official 2.0 release, hopefully next week or so.
