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.

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.

Hey Logan, this is with 1.16.43.0 firmware? 

Hey Casey/Manoj, is there some other sw or fw change missing for the ingpad change?  Or maybe something needed in the firmware config file?

Thanks,

Steve.
