[openib-general] failed to allocate buffer page

[Grant Grundler]

Hi,
Haven't checked yet waht the "side effect" of this error was,
but here is the output so people are aware of it.

This is the first time I've seen this. I've been doing
(unload, reload, test) loops alot last week. Just scripted
the set of commands and got the error on the first try.

Not reproducible on this or other boxes.
