I have the feeling that we might simply miss kernel support and it's not handled gracefully ... > 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, -- Shuah
