Hi Karl,

Regarding Petr's comment [1] as well, I'm concerned about the potential impact when the clk remains enabled during periods without console output.
When creating nbcon patch, I saw a similar patchh [2] from the past.
Have you considered coordinating with the clk subsystem implementation for this?
