I had the bot bisect these failures, results below.

The bisection pointed d2318f340253 ("arm64: dts: berlin4ct: add
watchdog nodes") which is clearly a red herring. kernelci.org inserts
the modules from the build into the ramdisk, and eudev will probe
them. With the modules inserted into the ramdisk, it fails to reach a
user space prompt. If I remove the modules from the ramdisk it boots
fine[1]. I may manually bisect if we cannot spot the issue easily.

The bisection pointed to b02ec7658c98 ("ARM: multi_v7_defconfig:
Enable some drivers for LS1021A")

I've rebased my tree with arm-soc for-next, and reverted the commits
listed above. Should know shortly if the reverts fix the boot issues.

Indeed, I'll look into this. Thanks for reporting.
