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
[ 155.434634] pwq 0: cpus=0 node=0 flags=0x0 nice=0 active=1/256
[ 155.437904] pending: cache_reap
[ 155.449671] workqueue events_power_efficient: flags=0x82
[ 155.458000] pwq 2: cpus=0 flags=0x4 nice=0 active=3/256
[ 155.461269] pending: neigh_periodic_work, do_cache_clean, check_lifetime
but you're getting hung up on the testsuite problems.
