I think I will disable CONFIG_CAN before v4.12. It causes too many
false results for v4.12..v4.11 range. It always leads to a wrong
decision for first 3 steps, then no chances of correct bisection
anymore.

The same seems to show up for v4.12..v4.13:
all runs: crashed: INFO: trying to register non-static key in can_notifier
https://syzkaller.appspot.com/text?tag=Log&x=1555b12b200000
This was fixed by 74b7b490886852582d986a33443c2ffa50970169 right?
