I restarted with stock 10.0 XEN3_DOMU kernel to get dtrace working
(it does not), but now the problem seems to have vanished. I run
with two vcpu and timecounter xen_system_time, ntpd syncs without
a hithch. This is a bit frustrating. Perhaps it needs more load
to fail.

Loading dtrace module fails on this:
kobj_checksyms, 1004: [solaris]: linker error: symbol `sdt_provider_sdt' not found
WARNING: module error: unable to affix module `solaris', error 8
WARNING: module error: recursive load failed for `dtrace' (`solaris' required), error 8

I cannot find sdt_provider_sdt anywhere in kernel sources.
