Hello,

Another cxgb4 bug report for you. Testing nvmet over our T62100-LP-CR
stopped working in v4.12-rc1. We are seeing two oopses: a general
protection fault in nvmet_rdma_free_rsps and a WQ_MEM_RECLAIM warning.
These occur after a suspect cxgb4 message. Please see the full dmesg log
which is attached.

> [   41.093555] cxgb4 0000:07:00.4: AE qpid 1034 opcode 0 status 0x1 type 1 len 0x0 wrid.hi 0x0 wrid.lo 0x0
> [   41.093673] nvmet_rdma: received IB QP event: QP access error (3)

I've bisected to find this commit is the culprit:

bb58d079: cxgb4: Update IngPad and IngPack values

A bisect log is also attached. Reverting that commit also fixes the issue.

Thanks,

Logan
