[Lustre-discuss] RHEL5's OFED with lustre1.8.2 on IB

[Lawrence Sorrillo]

I will definitely look into the hardware issues.

Also, I can't get (I have looked everywhere)

kernel-2.6.18-164.6.1.0.1.el5.x86_84.rpm

Our RHN services only proivdes kernel-2.6.18-164.6.1.el5.x86_64.rpm

Cheers,
~Lawrence
