As seen in some aarch64-debian-sid jobs like.

command timed out: 600 seconds without output running [b'sh', b'-c', b'cd mysql-test && exec perl mysql-test-run.pl --verbose-restart --force --retry=3 --max-save-core=1 --max-save-datadir=1 --max-test-fail=20 --mem --parallel=$(expr 25 \\* 2) '], attempting to kill
 
process killed by signal 9

This hard kill off by buildbot give no indication as to which test it is currently running.

The mtr testcase-timeout=MINUTES Max test case run time (default 15) should always be less than this. Setting testcase-timeout=8 and keeping the 600 second ( 10 minute) output timeout should allow mtr to kill off stalled tests and report their failure.
