Hi!
I'm here again :( So, Ian Pratt ask me to send this letter to the list
and I'm sorry for a long letter.
My computer is NEC Express5800 120Eg, which contains Intel SE7320SP2 SMP
capable motherboard with one cpu and two giga ram.

I'm using an Amd64 Debian Sid, the current versions of libc6 and others:

The first test without xen seems to be good (this kernel compiled on
this machine):

I updated xen today and built from scratch:

Xend with the recent
After this I boot the xen kernel (dom0 only) and I experienced a strange
clock skew again.

Yes, this was only 37s, not 120s!!
I tried this in domU and I got same result.
