The problem is that the Arbel driver is missing support for RC queue pairs; I thought I had added this at the same time as Hermon RC support but I was wrong. I have an Arbel card plugged in at the moment and have added RC support, but I'm hitting a strange error. Upon posting the first send WQE on the RC QP, part of the QP context is immediately corrupted; QUERY_QPEE shows that the value of snd_wqe_base_adr_l has changed from 0x3e781280 (correct) to 0xf3ee0040. Nothing else has changed, and the QP is still in RTS state. A completion arrives on the CQ with wqe_adr set to 0x00000000. Itay: any idea what might be causing this? On a related note, do you have a list of what the various vendor syndrome values in error completions mean? Thanks, Michael
