I am trying to run detect-mc-mapping.sh as described in the readme to detect the bank bits. I first tried on kernel 4.15 (the default for Ubuntu 16.04 with HWE), but it fails as described in issue #10.
So I booted into 4.10:
Linux 9550-linux 4.10.0-42-generic #46~16.04.1-Ubuntu SMP Mon Dec 4 15:57:59 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
but now I get:
$ sudo ./detect-mc-mapping.sh
mc-mapping: no process found

It seems the background processes fail to start due to segfault, which in turns makes the detection fail.
dmesg shows the following errors, corresponding to the segfaults:
