Good bug. The report looks good
Any chance you could add ftrace_dump_on_oops to command line and start this test
with tracing enabled? Otherwise, getting the line via addr2line of select_task_rq_fair+0xac8/0xca0
would be helpful.
It would also be nice to know the CFAR value (CFAR: c0000000000089e0) using
addr2line
