Under heavy load the Debian Kernel 4.14-13 crashes on high memory load and let the CPU freeze. Not really funny so rollback to older version
Apparmor has a current bug with the Kernel 4.14 on Debian and seems Ubuntu too, it blocks MySQL and other services from clean run. Bug touches Network Stack of the Kernel
After Ubuntu published the latest Kernel Patches for Meltdown and Spectre the Kernel 4.4.0-104/109-generic let Intel Graphics freeze or hang on Compiz with Unity. Howto fix: Install the latest Kernel 4.4.0-112-generic do: sudo apt-get install linux-image-4.4.0-112-generic sudo apt-get install linux-image-extra-4.4.0-112-generic reboot then: sudo apt-get autoremove –purge -y This removes older kernels and save Space! Do test the PC for hanging again!!!
