Any updates on this? If we don't get a patch for this soon, it will be deferred to 5.7.
Deferring to 5.7 based on where we are in the 5.6 dev cycle and what we have in hand.
*** This bug has been marked as a duplicate of bug 660375 ***
Even though this looks like a bnx2 upgrade issue, it is a much more complex problem and so this is not a duplicate of 660375. As this bz states above, on AMD systems with a bnx2 NIC, with scatter gather enabled, and not passthrough disabled, there is a problem transmitting. In my opinion, the problem is not solely in bnx2. Putting back to ASSIGNED state.
May be related to bug #663509.
Yes Michael, I believe you are correct about bz663509. Since bz663509 is closed errata in RHEL5.6, I will try to reproduce it but if anyone has any info on it, I would appreciate an update.
I disabled Passthrough on a AMD Dinar system via the amd-iommu=share cmd line option and found the problem did not happen. Given that the original problem manifested when files were transmitted to another system, I copied a bunch of rpms without issue. I copied the files back from the remote system successfully also. Scatter gather was also enabled while testing. See below for details. Note: amd-iommu=isolate worked too. Thus I am setting this a duplicate of bz663509.
