[ewg] Unexpected behavior with event channel

[Sean T Price]

Has anyone seen an issue with completion queues not delivering events for
solicited completions when initialized for solicited only. Our code no
longer sees solicited events on our event channels on a system with a
MHQH29C-XSR/XTR mellanox card running RHEL 5.6. We have not seen this
problem on other systems running RHEL 5.5 with ConnectX and ConnectX2
hardware.

We have seen the items in the completion queue but the file descriptor
associated with the event channel does not cause the call to select to
unblock.

We have tried our software with the RHEL supported IB packages and the
Mellanox OFED 1.5.3 for RHEL 5.6.

Any suggestions on where our configuration may be in error would be
appreciated.
