I think you've got the wrong bisection point, confused by other messages.
Here's the messages I think you intend to chase:

[  155.389297] BUG: workqueue lockup - pool cpus=0 node=0 flags=0x0 nice=0 stuck
 for 52s!
[  155.409004] BUG: workqueue lockup - pool cpus=0 flags=0x4 nice=0 stuck for 40
s!
[  155.420377] Showing busy workqueues and worker pools:
[  155.428445] workqueue events: flags=0x0

[  155.461269]     pending: neigh_periodic_work, do_cache_clean, check_lifetime


but you're getting hung up on the testsuite problems.
