With the former kernel 2.6.26-19lenny2, it works. It must be > related to either amd64 and/or xen kernels beside maybe others.

In particular, the time adjustment code that copes with leap seconds could trigger a deadlock. It is possible that this is not compatible with the Xen feature patch. > I tried to start klogd with option -s without success.
