I have the same experiences. My SMP machines run very stable with 2.0.36,
but newer kernels give me problems. I need stability so I'm stuck for now
with the 2.0 kernels.
Just thought I'd let you know your not alone.

Subject: Re: possible use of a linux cluster
I have set up a cluster of 16 dual processor boxes for Monte Carlo
simulation
at my company, each running SMP-Linux. I use PVM both within and across
boxes
to run parallel applications. I experimented a while ago with using threads
within each box, and PVM or MPI for message passing across boxes,
but I found out that neither of these pieces of
software work well with threads.
After I inquired, I was told by people who were involved in supporting
these two packages, that they knew of no reason why these packages would
be incompatible with threads, but they are. I was also told that there
was some work underway to address this, but apparently nothing has been
done.
By the way, I am still using an Oooold kernel (2.0.36) compiled with SMP,
because the last official (albeit development) SMP kernel
I tried (2.1.15 or so) gave me trouble.
My PVM applications would run only if compiled under the old kernel.
Mind-boggling!! Has anybody looked into this?
