Is it possible you're on the right track, but manifests differently on our 
two systems? :-)

Last semester we were running 3.0.20 on this machine. We've been toying 
with going back to that code base to see if it stabalizes. (Of course 
putting deadtime back to zero for the test.) That still has me confused as 
to why the non-zero deadtime seems to make the whole environment more 
stable. It's the *only* modification we've made that has had any impact at 
all.

If 3.0.20 fails, then it's most likely a kernel bug. It's so hard to get 
IBM to move on this without *ahem* additional compensation. I even got the 
duty manager involved on the PMR since I got the brush-off.

I would appreciate any more info you have on the fcntl bug you mentioned 
so I can run it by IBM. I think on Monday we'll try 3.0.20 and see what 
happens.

cheers,

Bill
