In a fresh cauldron install, most of the sysrq key sequences now result in a message saying that this sysrq function is disabled. This started happening many years ago, and was supposedly a deliberate change done to prevent inexperienced users from using them accidentally. Hue and cry was raised, and the "feature" was quickly reverted and has stayed reverted until now. I have no idea how this got reintroduced, and I seem to remember that it was easily fixed manually for each boot by resetting something in /proc (I can't remember what). Please revert this to the historical behavior.
Thank you for the report. This goes back to 2012, M2 (bug 6842)! The probable bug Frank mentions is bug 10473 2013/14 Mageia 4. Having not seen Sysrq mentioned before, it would be nice to either say where its use is documented; or summarise that use here for the benefit of others. Combined with Alt seems common.
