I am not seeing infinite loops and seeing 25 failures which could
be skips.

Here is my config
CONFIG_HMM_MIRROR=y
# CONFIG_TEST_HMM is not set

Okay here is what is going on - hmm_tests are supposed to be run
from test_hmm.sh script. When I run this I see a message that tells
me what to do.

sudo ./test_hmm.sh
./test_hmm.sh: You must have the following enabled in your kernel:
CONFIG_TEST_HMM=m

Running ./hmm_tests gives me all the failures. So it appears running
hmm_tests executable won't work. This is expected as test_hmm.sh does
the right setup before running the test. We have several tests that do
that.

Vlastimil, can you try this and let me know what you see. I will compile
with CONFIG_TEST_HMM=m and let you know what I see on my system.

thanks,
