Dave,
Which driver is active? Which Infinipath software release
is installed? The tool "ipath_control -i" can show which...
The kernel.org/ofed driver does not have as rich a set of error recovery
code for this card as the shipped driver. The recovery code was seen
as a badness and not accepted by the kernel.org folk....
With a kernel update the driver will not have been recompiled
and the kernel.org driver would become active.
Look for this stuff in the Install Guide.
# To rebuild the drivers, do the following (as root):
# cd /usr/src/infinipath/drivers
# ./make-install.sh
# /etc/init.d/infinipath restart

Got a great hat... now what.
