Hello Laurence, This issue can be reproduced as follows: * Clone the block-scsi-for-next branch from https://github.com/bvanassche/linux (commit cd0b6b9f8779). * Clone the srp-test project from https://github.com/bvanassche/srp-test. * Modify /etc/multipath.conf as indicated in the README.md file of the srp-test project and restart multipathd. If you prefer the rdma_rxe driver, run the following command: srp-test/run_tests -c -d -r 10 -q 1 -t 02-mq -e kyber Or if you prefer to run the test against an IB driver (mlx4, mlx5, ..) on an IB system, run the following command: srp-test/run_tests -d -r 10 -q 1 -t 02-mq If running one of the above commands once would not be sufficient to trigger the lockup, rerun the command a few times.
