hi!
Same; this is breaking on my Snapdragon X1E FDT BSP work.
It fails super early in kernel hand-off. It's going to be a pain to
figure out locally as I have a framebuffer and I'd have to go do all
the early mapping to do super early (in initarm()) framebuffer work.
Is this reproducible by anyone else? delphij@, do you have any arm64
FDT devices? Or maybe QEMU?
bz@ and lwhsu@ did some diagnostic work, and this should help (adding
-DZSTD_NO_TRACE to ZSTD_C)

MFV: zstd 1.5.7.
MFC after: 2 weeks
Relnotes: yes
I do not know how but this makes an arm64 machine,
doing a UEFI netboot (in case it matters) fetching the /boot/loader.efi,
to fail.
Kernel is the GENERIC-MMCCAM and I do not do ZFS, just to be sure.
