> We were able to reproduce this issue internally only with iommu enabled.
My last test to collect lspci-info took about 5 hours over a gigabit network for the bug to show up. My setup was running 3 tx scp sessions, each transferring a 1GB file outbound, and 1 rx scp session copying another 1GB file inbound. In a production environment with the BCM5762 NIC running as a server, I observed that the failure rate is about 1.65/week. Please perform a similar test with iommu disabled, and leave it running for days if need be. > Meanwhile can you try the attached patch and see if you are able to > reproduce the problem ? No problem. I will apply the patch to kernel 4.0 and report back the result. Let me know if you need me to turn on any debug options like pcie trace, dev debug etc....
