Working off of release 2.6.2, I found a reproducible segfault in
ib_close_connection
by doing `pvfs2-ls` (ppc64-openib) hardware appears to be functioning
properly, and have reproduced on both eHCA and Mellanox cards. I'm doing
netpipe over ib right now.
heres the backtrace:
[E 15:53:25.692442] Warning: exchange_data: partial read, 1/4 bytes.
Program received signal SIGSEGV, Segmentation fault.
