Hi,

main-n245392-8423f5d4c12 built 11th March won't boot due to microsd timeout.

A kernel.old made from main-n244802-88db1cc9f19 on the same sdcard with the
same rpi4b hardware and the same materials on the msdos partition does not have
this problem.

These are no-debug kernels, built with the same kernel config file. I have
tried booting without anything attached to usb and it still fails at the same
place. Running fsck on the microsd in another machine for both the msdos and
the freebsd partitions makes no difference.

Full console output is at
