kmod-kvdo-6.2.4.26-75.el8 has been generated to address kernel-4.18.0-242.el8. kmod-kvdo-6.2.4.26-75.el8 does not work with kernel-4.18.0-255.el8. A new build of kmod-kvdo has been generated and will be in the next nightly compose. kmod-kvdo-6.2.4.26-76.el8 is the NVR for that build. *** Bug 1904034 has been marked as a duplicate of this bug. *** This affects CentOS 8 stream s well, I cloned this bug as bug 1907968 Our CI hasn't seen this now for 21 days, so it seems to be fixed now. This BZ exists to allow me to quickly address the problem if/when it occurs again. I do not intend to close it until the release has been completed just in case it does come up again. kernel-4.18.0-294.el8 introduced some symbol changes to dm-bufio, requiring a kmod-kvdo rebuild. A new build is in the works.
