[Alexander Tarkhov]

David,

An overview would be like this:
There is a work-around that works in some cases -- upgraded Scyld driver
or driver from chip vendor.
There is no pretty much explanation and even less resolution to this
problem.
It seems like the problem originates from so deep into the chip design
and architecture, that it's just
not worth explaining in list like this - something about hw being
ready/not ready in unpredictable times.
(God, what happend to my English?)

But what is good about your case - you are the first to report about
multiple failures ("...some of the nodes...").
Because what we have seen before were just distinct unlucky specimen...
(Can't find the plural for this word in the Dictionary, pls. tell me
someone?)
So probably you experience real incompatibility of driver version /
kernel version,
which means the driver upgrade might help...

Good luck!
Alexander
