LKFT detected arm64 boot regression on today's Linux next-20221121 tag.
The Kernel boot log did not show anything on the serial console.
Anders bisected this problem and found the subject commit is the
first bad commit.
# first bad commit: [9ed2b4616d4e846ece2a04cb5007ce1d1bd9e3f3]
arm64/mm: Drop redundant BUG_ON(!pgtable_alloc)
Later it was found this lore link which was already reported [1].
