brocade 24000 and emulex lp9002 SBUS hbas

Has any one run into issues with emulex lp9002-s (sbus cards) maxing out at 50MBS? I'm seeing billions of tim_txcrd_x (time BB_credit zero) but no er_disc_c3 (Class 3 frames discarded)

I would look at the bus that the HBA is in. Possibly isolate the HBA on it's own bus if possible. Or at least ensure that the HBA is in the highest priority slot on the bus.We have everything from LP8000 up to LP9802s. I currently have a few HBAs pushing upwards of 145 MB/s on rare occasions.

I hope to have an update on this soon. I have verbal confirmation that there is an issue with the pci bridge chip on the card. Plan is to move back to one gig JNI cards, but double the amount.
