From the config provided, stmmac driver is not even enabled. Can you
please confirm the bisection process ?

Looks like a false positive, as j1939 (net/can/j1939/) hit mainline with
v5.4-rc1~131^2~78^2.
While the bisected commit is v5.3-rc1~140^2~13^2.
regards,
Marc

Yes, the commit is most likely irrelevant. As you can see in the
bisection log the process was diverged by "WARNING: ODEBUG bug in
netdev_freemem". I think it's not the first and not the second time I
see that crash breaks bisection:
