I've got that board as well and am seeing the issue too, the bisect
comes out at:

[c657c6cbac472125a03d7bfb6137e6e23ebb7081] net: stmmac: protect updates of 64-bit statistics counters

I'm also seeing bisects of similar boot failures pointing to the same
commit on at least i.MX8MP-EVK and Libretech Potato.  Bisect log for the
board Francesco originally reported, the others all look the same:
