I should add that I installed it from elrepo earlier today on a current computer, not some time ago... No error messages.

No error messages. >?Try the following command on a computer you had kmod-jfs installed: ?$ ls -l `find /lib/modules -name jfs.ko` It will show where the module was installed (in the extra/ directory) and may show symbolic links to other kernel versions (if any) that are compatible. In the case of the kmod-jfs package, there was a kABI breakage when going from el7.3 to el7.4. As a result, what was built against el7.3 was broken in el7.4. It has now been built against the el7.4 kernel. This one is not backward compatible with earlier (< 7.4) kernels. Akemi

How long time does it typically take for an updated package to become available?
