The Oops at the top of the report is secondary and uninteresting. After the
first Oops, the system is in an unstable state. That's documented in the oops
because it's tainted "D."
The invalid opcode message is there because that's how BUG() is implemented. It
sets up the strings for the location of the call and then causes an invalid
opcode exception, which is handled specially.
The interesting Oops is the one from the log. Here it is, cleaned up a bit:
