[Lustre-discuss] ko2iblnd panics in kiblnd_map_tx_descs

[Canon, Richard Shane]

Chris,

Which headers did you point lustre to?  Try using the non-version one (ie ofa_kernel not ofa_kernel-1.2.5.5).

I'm trying to port Lustre 1.6.4.2 to OFED 1.2.5.5 w/ the RHEL kernel
2.6.9.67.0.4.

ksocklnd-based mounts work fine, but when I try to mount over IB, I
get a panic in ko2iblnd in the transmit descriptor mapping routine:

Does this ring any bells?  Otherwise, any debugging tips?

Shane said that they get an oops if they compile with the "version
specific OFA tree".  Is this the Oops?

Thanks,

Chris
