1–Overview of the Release
Other Information
D000069-024 1-15
 Older QLogic InfiniPath 2.2.1 and prior releases will not be recognized in the
installation menus and will be treated as if no InfiniBand software is installed.
 When upgrading from an older QLogic OFED+ release to a new QLogic
OFED+, the older QLogic OFED+ release will be uninstalled first.
 When installing the OFED Debug Info component, make sure that
~/.rpmmacros does not have any lines changing the %debug_package
macro.
If %debug_package is set to %{nil}, debuginfo RPMs will not be available
for installation.
The current setting for this parameter can be verified using:
rpm --eval '%{debug_package}'
If a non-blank output occurs, then debuginfo is enabled. If a blank line is
output, then debuginfo is disabled on the present system.
 When running QLogic SRP over two ports in round robin mode, performance
is degraded.
 When running verbs-based benchmarks such as ib_send_bw, the following
message may appear:
BUG: soft lockup - CPU#1 stuck for 10s.
This message does not impact completion or correctness of the benchmark.
 The ib_send_bw benchmark, when run in UC mode, is written such that it
will hang if even one packet is dropped.
 The QLogic 12000 series switch firmware must be at version 6.0.0.1.2 or
later to connect with the TrueScale Host Channel Adapters in this release.
 QLE7240/QLE7280 performance with Barcelona stepping B2 and the
BIOS/kernel workaround for AMD errata 298 can lead to reduced InfiniBand
bandwidth, as a result of poor memory bandwidth and latency on the
adapters due to the workaround. To fix this problem, upgrade to Barcelona
stepping B3 (or later).
