New server, installed 4.11-RELEASE ... hangs ...

[Marc G. Fournier]

Just built a new Dual-Xeon server, Intel motherboard ... put 4.11-RELEASE 
onto it, and I'm getting an odd behaviour that I'm wondering if anyone can 
give me a suggestion on where to look / investigate ...

Mainly, it looks like after a period of time (not very long), commands 
just stop running ...

For instance, I'm running cvsup to update my source tree (hoping that its 
just a bad kernel) and on another console, I login and do a 'ps aux', 
which  just hangs there ... on a third console, I can login and still do a 
df at the same time as that ps is hanging, but if I then do a ps, that 
console hangs ... if I then go to the 4th console, it hangs while logging 
in ...

I can get to a DDB prompt, but not sure what I can provide from there that 
may be useful ...

Thoughts?

Thanks ...
