Original GitHub issue: https://github.com/hirschmann/nbfc/issues/453

See this image below. Installed latest version of NBFC from Github (using AUR package: nbfc-git, which I maintain by myself).

The issue itself is seem to be related to the latest Linux kernel, because on current linux-lts 4.14.22-1 the NBFC works without problems (just had to downgrade ncurses due to #451 issue).

Hi,

My ArchLinux kernel is linux-ck 4.15.13-1.
After adding kernel parameter ec_sys.write_support=1, I can modify EC register.
Do you have tried adding this kernel parameter?
