Kernel upgrades may cause slight disturbances - 2018-01-10

During the coming days we will be upgrading the kernel on all systems due to the Meltdown/Spectre security bugs.

This may cause some interference in the normal behaviour of the systems like slow or temporarily missing file system access, stopped queues and similar.

We will try to minimize the user visible effects but this is a upgrade we must do as quickly as possible and may sometimes have to do things in such a way that the user experience is somewhat degraded.
