Hello Mike, The reported kernel crash was triggered by running the following command: srp-test/run_tests -c -d -r 10 -t 02-mq The srp-test software is available at https://github.com/bvanassche/srp-test. All patches necessary to run that script in a virtual machine (RoCE support for the SRP initiator and target drivers) will be sent to Linus during the kernel v4.17 merge window. These patches are already available in linux-next today. Although I have not tried this myself, I expect that if you run the above command against a kernel built from the linux-next code that that will allow you to reproduce what I reported. Thanks, Bart. -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
