I have no "irqbalance" daemon running, that's why the interrupts aren't distributed among CPU cores.
Below is the full contents of "/proc/interrupts" from my PineBook Pro, which is running Manjaro ARM, after about 12 hours of uptime and only one actual headphones plug-in event. The remaining 22 are spurious.
My initial research points into the direction of a possible hardware issue, but I'll stay away from spending a lot of time and digging deeper until we actually have it confirmed as an issue.
By the way, what does the "intrctl" utility actually do? I'm not familiar with it and a web search returns only NetBSD references?
