Just in case this helps anyone else: we hit the MDS panic in jbd2/dm-0-8 reported above with b2_2. We tracked the root cause to LU-1823, slab corruption.

As per Peter, we don't have any plans to land anything to b2_2 at this time. We can add Lustre version check code in b2_3 and master test suites to skip the test as what we did in LU-1912.

ok then let's drop this from being a blocker unless it reoccurs and we are able to gather the diagnostic information from the logs.

In the latest tag 2.2.92, subtest 103 passed on both RHEL5 and RHEL6 client
