So pushed an updated hmm-next branch this should fix all issues you had.
Thought i am not sure about the test in this mail, all i see is that it
continously spit error messages but it does not hang (i let it run 20min
or so). Dunno if that is what expected. Let me know if this is still an
issue and if so what should be the expected output of this test program.

Thanks, Jerome. The kernel hang indeed seems to be fixed.
Regarding the last issue I reported. It still persists. The test program
should eventually exit. Instead, it loops indefinitely (sorry, I was not
clear when I called it 'app-side hang').
This is what's expected. The number of error messages can be random, but
must be finite; the program must print "OK" at the end:
$ ./run.sh
