Sure, though from our point of view, they never were. Good riddance to
that cluster vendor, who should have gone out of business earlier.

I suspect I had done the experiment too.

In case it helps for anyone else trying this with old kit: I had been
using a v6.something, but I'd have to check the something. Using the
set of "updates" modules built with that and the latest kernel also
provokes the crashes, binary compatibility or not.

Understood, and thanks.

Sure, and presumably the Red Hat module shouldn't match the hardware if
it won't work. (The kernel supports the even older QHT cards OK -- pity
anyone running an old cluster with Mellanox added to three incompatible
lots of Infinipath and ethernet islands.)
