[CRIU] criu check --extra output and dump failure

Hello,
I am trying to get criu to do something on an "armv7l GNU/Linux"
platform. I am running a 4.4.8 kernel. I think I successfully selected
the options you mention in https://criu.org/Installation .
This is what I get when I run the first checks:
root at POWERScope:~ criu check
Looks good.
root at POWERScope:~ criu check --extra
Warn (criu/cr-check.c:705): Dirty tracking is OFF. Memory snapshot will not work.
Error (criu/tun.c:61): Can't check tun support: No such file or directory
Error (criu/cr-check.c:919): cgroupns not supported. This is not fatal.
Error (criu/cr-check.c:1021): The TCP_REPAIR_WINDOW option isn't supported.
Error (criu/cr-check.c:965): TCP_REPAIR can't be enabled for half-closed sockets
Error (criu/cr-check.c:1035): No userns proc file: No such file or directory
Warn (criu/cr-check.c:1054): Loginuid restore is OFF.
Looks good but some kernel features are missing
which, depending on your process tree, may cause
dump or restore failure.
Do I need to get worried by this?
It seems I do, because when I run the example on
https://criu.org/Simple_loop with setsid, even just dumping this simple
program fails:
root at POWERScope:~ setsid ./test.sh < /dev/null &> test.log &
root at POWERScope:~ ps -C test.sh
PID TTY TIME CMD
746 ? 00:00:00 test.sh
[1]+ Done setsid ./test.sh 0</dev/null 1>&test.log
root at POWERScope:~ tail -f test.log

And now I am totally stuck. Everything I do ends with an "unexpected
signal 11" after injecting the parasite blob and I couldn't find any
hint about what to do then.
The ultimate aim is to dump and restore a Chromium "content_shell"
process. Is something of that order reasonably achievable with criu or
have I wasted my time trying to get this far?
Kind regards
