The dmesg trace is attached. Thank you for having shared the dmesg output. If the test setup is still in the same state, please try to run the following command: $ dmsetup ls | while read a b; do dmsetup message $a 0 fail_if_no_path; done If this resolves the hang, this hang is not a kernel bug but a bug in multipathd or in the test scripts. Thanks, Bart. Help. Do I run after the hang (from a different shell) or before I run srp/002? Bob
