I need to be able to reproduce it here in my lab, and so far I havn't
had any luck with that. There also doesn't seem to be any easy to find
denominator between the systems that fail...

The problem is probably timing related, perhaps I have gotten something
a wee bit out of spec, but not enough for all systems to fail...

Anyhow this is a bitch to debug....
