That seems to be a NULL dereference (0e = page fault, cr2 0 =
dereferenced address).

$ addr2line -e vmlinux -i ffffffff802c9abd

This should print the name of the function that crashed. If you enable
CONFIG_DEBUG_INFO you can get the exact line number info too (but
remember to replace the ffffffff802c9abd with the new value if you
recompile and run it again).

the programmer was not looking is intellectually dishonest as it
disguises that the error is the programmer's own creation."
