Today's -next failed to boot on peach-pi:

with details at https://kernelci.org/boot/id/5a2a2e7859b5141bc2afa17c/ (including logs and comparisons with other boots, the last good boot was Wednesday). It looks like it hangs somewhere late on in boot, the last output on the console is:

and there's failures earlier to instantiate the display.
I just noticed that further up the log there's a lockdep splat with a conflict between the genpd and clock API locking - an ABBA issue with genpd->mlock and the clock API prepare_lock.
+Cc Marek Szyprowski,
The lockdep issue and display failures (including regulator warning) were present for some time. They also appear in boot log for next-20171206 (https://storage.kernelci.org/next/master/next-20171206/arm/exynos_defconfig/...). The difference is that 20171208 hangs on "random: crng init done" which did not appear before at all.
The only recent changes in samsung-soc tree which could affect Exynos5800 is - ARM: dts: exynos: Add audio power domain support to Exynos542x SoCs https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux.git/commit/?h=nex... - ARM: dts: exynos: Add CPU perf counters to Exynos54xx boards https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux.git/commit/?h=nex...
But both of them were present in next for few days so they should hit 20171206 as well.
Maybe the issue comes from different subsystem?
Best regards, Krzysztof
