When I trigger these errors, it seems to corrupt one or more of the script associated with the SALFTER functions, and I have to re-image, update, recompile to get them to work again.
I think the global powerlimit/OC function is also incompatible, but the issues with some kind of corruption make it time consuming and difficult to troubleshoot.
I have tested this with a 16GB usb stick, a 180GB Intel SSD, and a 500GB HDD so I am sure that the OS media is not the issue.
Everything else is brand new and exhibits no instability running the default config (untouched 1bash)
