[openib-general] [Bug 229] heavy CPU load can starve ib_mad thread on latest processors

[Michael S. Tsirkin]

Hmm, OK.
I'd like to figure out whether this could be something other than a scheduler
issue.
Could you test on kernel 2.6.18 or 2.6.17 please?
If this is a scheduler issue, there's a chance scheduler is more fair there.
