Public bug reported: == Comment: #0 - BRYANT G. LY - 2017-01-16 10:35:29 == ---Problem Description--- Ibmvscsi Target driver isn't working properly due to a bug where we are sleeping in an interrupt context, also the max transfer length is incorrectly assuming 4k page tables instead of 64k for ppc64. ---Steps to Reproduce--- Use TCMU-Runner with AIX clients Stack trace output: Dec 27 18:10:45 reeknova kernel: [315412.636895] ibmvscsis 3000000b: rdma: h_copy_rdma failed, rc -11 Dec 27 18:10:45 reeknova kernel: [315412.636895] ibmvscsis: srp_transfer_data() failed: -11 Dec 27 18:10:45 reeknova kernel: [315412.636898] ibmvscsis 3000000b: rdma: h_copy_rdma failed, rc -11 Dec 27 18:10:45 reeknova kernel: [315412.636899] ibmvscsis: srp_transfer_data() failed: -11 Dec 27 18:10:45 reeknova kernel: [315412.636902] ibmvscsis 3000000b: rdma: h_copy_rdma failed, rc -11 Dec 27 18:10:45 reeknova kernel: [315412.636902] ibmvscsis: srp_transfer_data() failed: -11
Need three of these patches back ported to 4.4 kernel / 4.8 kernel. It has all been queued up for 4.10 kernel under target-devel subsystem. == Comment: #3 - BRYANT G.
