The widespread kernel hang issues are still seen. I managed
to bisect it after working around the transient build failures.
Bisect log is attached below. Unfortunately, it doesn't help much.
The culprit is reported as:

2d542828c5e9 Merge remote-tracking branch 'scsi/for-next'

The preceding merge,

453f1d821165 Merge remote-tracking branch 'cgroup/for-next'

checks out fine, as does the tip of scsi-next (commit 103c7b7e0184,
"Merge branch 'misc' into for-next"). No idea how to proceed.
