Yes. Thank you very much for cc. me and the very useful explanation of
how to read the log!

Hmm, this is another bug for RTDS on ARM. :-(
I don't have an ARM board set up right now. I'm not sure if I can
run/test it on ARM. I'm curious if this bug is similar with the
previous lock-related bug of RTDS scheduler on ARM.
Denys fixed the previous bug at
