Linux on Dell 7490

Don’t miss to add kernel options i915.enable_dc=0 and intel_idle.max_cstate=1, if you want to run a modern arch linux on your Dell Latitude 7490.

Reduce Kernel Messages in rsyslogd

In the standard rsyslog setup of Ubuntu a kernel message goes to 3 log files (syslog, messages and kern.log), i.e. running LOG targets in your firewall setup can really hog your /var/log volume.

I decided to simply discard the kernel messages after logging them to kern.log.
