+1. Overview
+======================================================================
 ipath is the low level driver implementation for all QLogic InfiniPath
 HCAs: the HTX QHT7140, the PCI-Express x8 QLE7140, the PCI-Express x8
 DDR QLE7240, and the PCI-Express x16 DDR QLE7280.
 
+======================================================================
+2. Fixed Bugs and Enhancements
+======================================================================
+2.1 (Bug 1283) Intel MPI fails on Qlogc HCA
+
+Added memcpy_cachebypass support to IB/ipath
+----------------------------------
+2.2 (Bug 1117) ib_ipath module hangs on unload.
+
+This fix handles the case where posting a send is requested when the 
+link is down.
+----------------------------------
+2.3 (Bug 1093) Compile fails because definition of valid_dma_direction 
+is missing from file ipath_dma.c
 
-1. MSI (Message Signalled Interrupt) support required with
+Marked as RESOLVED INVALID. XEN is not a supported kernel. It defines 
+its own dma-mapping.h file and any driver which uses DMA probably 
+needs to be modified to work specifically within XEN.
+

+3. Known Issues
+======================================================================
+3.1 MSI (Message Signalled Interrupt) support required with
    QLogic InfiniPath HCAs
-----------------------------------------------------------
+
 The QLogic InfiniPath adapter requires MSI (Message Signalled
 Interrupts) to be enabled in the kernel.
 
-1.1. If the InfiniPath driver is intalled on a machine without
+If the InfiniPath driver is intalled on a machine without
 CONFIG_PCI_MSI=y configured, a warning similar to this will appear in
 dmesg at boot:
 
 [root@sqa-00 ~]# dmesg | grep ipath
-  ib_ipath 0000:01:00.0: infinipath0: QLogic PCIE device 0x10 cannot work if 
-  CONFIG_PCI_MSI is not enabled
+  ib_ipath 0000:01:00.0: infinipath0: QLogic PCIE device 0x10 cannot 
+  work if CONFIG_PCI_MSI is not enabled
+----------------------------------
+3.2 (Bug 1369) No results when running Open MPI bandwidth with msg size 
+bigger than 2200 with Qlogic HCA
+
+OpenMPI defaults to the IB MTU size specified in a configuration file 
+found within the OpenMPI install directory at:
+
+  share/openmpi/mca-btl-openib-hca-params.ini 
+
+This file contains a mapping from adapter cards (identified by vendor 
+ID and adapter part ID) to MTU size. Note that this is a static 
+mapping and the available MTU on a particular fabric might not be the 
+same as the maximum supported by the adapter card. This could happen 
+due to switch MTU limitations, or use of different adapters. In this 
+case the value should be set to the largest value that works for 
+all HCAs and switches in the IB fabric (that will be part of the 
+OpenMPI job).  If the value specified is too large, the job will 
+typically hang at run-time without a diagnostic.
+
+Current workaround: The two ways to work around this would be to 
+either set your switch to run with a 4K MTU, or to edit the 
+mca-btl-openib-hca-params.ini file and hardcode the MTU for 
+InfiniPath (TrueScale) adapters to 2K.
+
+This will be resolved by joint effort between QLogic and OpenMPI.

+3.3 (Bug 1242) Kernel panic while running mpi2007 against 
+ofed1.4 -- ib_ipath: ipath_sdma_verbs_send
+
+Found while running mpi2007 over OpenMPI on stock OFED1.4 RC1 RHEL4.X
+machines. QLogic is working on it. Contact support@qlogic.com if you
+run into this problem.
