hey, after what upgrade? Usual `dnf upgrade/distrosync`, fedup or fedora upgrade (which versions). Attach the output from transaction, please. Then we can assign it to right component. Thanks.

I too experienced this today morning and saw the kernel boot entry showing garbage characters but as I was not having time to debug it I just boot into previous installed kernel and system is working fine. I think the bug should be related to kernel package but other side dnf history does not show any scriptlet failure output for that upgrade transaction. Following are the related entries from that transaction Erase kernel-4.0.0-0.rc4.git0.1.fc22.x86_64 @updates-testing Install kernel-4.0.0-1.fc22.x86_64 @updates-testing Erase kernel-core-4.0.0-0.rc4.git0.1.fc22.x86_64 @updates-testing Install kernel-core-4.0.0-1.fc22.x86_64 @updates-testing Erase kernel-devel-4.0.0-0.rc4.git0.1.fc22.x86_64 @updates-testing Install kernel-devel-4.0.0-1.fc22.x86_64 @updates-testing Upgraded kernel-headers-4.0.0-0.rc5.git4.1.fc22.x86_64 @updates-testing Upgrade 4.0.0-1.fc22.x86_64 @updates-testing Erase kernel-modules-4.0.0-0.rc4.git0.1.fc22.x86_64 @updates-testing Install kernel-modules-4.0.0-1.fc22.x86_64 @updates-testing Erase kernel-modules-extra-4.0.0-0.rc4.git0.1.fc22.x86_64 @updates-testing Install kernel-modules-extra-4.0.0-1.fc22.x86_64 @updates-testing Upgraded kernel-tools-4.0.0-0.rc5.git4.1.fc22.x86_64 @updates-testing Upgrade 4.0.0-1.fc22.x86_64 @updates-testing Upgraded kernel-tools-libs-4.0.0-0.rc5.git4.1.fc22.x86_64 @updates-testing Upgrade 4.0.0-1.fc22.x86_64 @updates-testing Upgraded kernel-tools-libs-devel-4.0.0-0.rc5.git4.1.fc22.x86_64 @updates-testing Upgrade 4.0.0-1.fc22.x86_64 @updates-testing
we are unable to reproduce it and so I am closing this. If you encounter this again, reopen and attach the dnf transaction output, please. IMO still not DNF bug if transaction succeeds.
