Which version of CRIU do you use?

I fixed this issue by these commits:
https://github.com/xemul/criu/commit/b6d9bcd10d576ca9e5a60be2b8218c35edcd5931
https://github.com/xemul/criu/commit/64744030f29f138d879b46de278f6cf9ea629b9e

FYI: zdtm.sh is deprecated. Now we recomend to use zdtm.py.

For example, if you want to execute all test:
./test/zdtm.py run -a

or if you want to execute only one test
./test/zdtm.py run -t zdtm/live/static/rtc

Now "make test" uses zdtm.py to run tests too:
https://github.com/xemul/criu/commit/cba08fb788f48e3d8e43abb5d24426691b25a57d

Thanks,
Andrew.
