dmesg of previous kernel that works
Works with kernel-headers-4.1.6-201.fc22.x86_64 kernel-core-4.1.6-201.fc22.x86_64 aernel-modules-4.1.6-201.fc22.x86_64 I was able to reproduce the behaviour by installing only kernel-core-4.1.7-200.fc22.x86_64 without the corresponing kernel-modules rpm. Dnf allowed me to do that without complaining about missing dependencies. After I installed only kernel-core, I found: The system would not power off from the screen menu. When I tried a poweroff command as root, I got an error message and no power-down.init 0 gave the usual warning to all consoles, but nothing further happened. After powering-down manually and restarting in kernel-4.1.7, there was no wifi menu available. I shut down and restarted in kernel-4.1.6. I removed 4.1.7 and tried to install only kernel-modules-4.1.7. I got a dependency message. When I installed both kernel-core-4.1.7 and kernel-modules-4.1.7 and restarted in kernel-4.1.7, the system works fine. There are two possible bugs here: 1) Failure to power down when only a new kernel-core is installed 2) Ability to install and run only a different kernel-core. Seeing the great degradation of the system, I would have liked a warning when I did that. The ability to install only kernel-core is intentional. That is how our cloud products install a minimal kernel image. For normal machines, such as a desktop or laptop, the default install has 3 packages: kernel kernel-core kernel-modules The kernel package requires both kernel-core and kernel-modules. If your machine is lacking the kernel package, you likely removed it at some point. There is still no bug here. |
