[ofa-general] Cannot bring up mellanox HCAs on HP Nahalem machines running RHEL 5

[Mike Heinz]

We've open an OFED PR ( https://bugs.openfabrics.org/show_bug.cgi?id=1663 )
on this issue, but I'm wondering if anyone else has seen this: We just got
some brand new HP "gen6" machines - and we cannot get any Mellanox HCA, DDR
or QDR to come up on those machines - if they are running RHEL 5.3. Machines
running SLES11 appear to work fine.

The same HCAs work fine on slower machines and on machines running SLES11 -
has anyone else seen this?

We're running OFED 1.4.1 GA.
