Tue Jan 10 08:14:40 PST 2023

[ please ignore this email if this regression already reported ]

Today's Linux next tag next-20230110 boot passes with defconfig but
boot fails with
defconfig + kselftest merge config on arm64 devices and qemu-arm64.

Reported-by: Linux Kernel Functional Testing <lkft at linaro.org>

We are bisecting this problem and get back to you shortly.

GOOD: next-20230109  (defconfig + kselftests configs)
BAD: next-20230110 (defconfig + kselftests configs)
