I got a couple of fail messages.
dmesg output is available in the bug as the following attachment: https://bugzilla.kernel.org/attachment.cgi?id=143361
The part of interest is probably:
[ 0.253354] build_sched_groups: got group f255b020 with cpus: [ 0.253436] build_sched_groups: got group f255b120 with cpus: [ 0.253519] build_sched_groups: got group f255b1a0 with cpus: [ 0.253600] build_sched_groups: got group f255b2a0 with cpus: [ 0.253681] build_sched_groups: got group f255b2e0 with cpus: [ 0.253762] build_sched_groups: got group f255b320 with cpus: [ 0.253843] build_sched_groups: got group f255b360 with cpus: [ 0.254004] build_sched_groups: got group f255b0e0 with cpus: [ 0.254087] build_sched_groups: got group f255b160 with cpus: [ 0.254170] build_sched_groups: got group f255b1e0 with cpus: [ 0.254252] build_sched_groups: FAIL [ 0.254331] build_sched_groups: got group f255b1a0 with cpus: 0 [ 0.255004] build_sched_groups: FAIL [ 0.255084] build_sched_groups: got group f255b1e0 with cpus: 1
I also booted with early printk=keepsched_debug as requested by Dietmar.
