Comment 46 for bug 1488426

So I see this is the Ubuntu bug tracker, yet I have the same in Solus, Kernel 5.2.9-125.current.

Not sure this is helpful, but I'll add my USB devices anyway in case it helps narrow it down.
This happens on an off, single core going to near 100% usage with USB PM to blame it seems. Would a perf report help?

This happened today, when I had a dell USB-C monitor plugged in, then 2 mice, a keyboard and a headset plugged in through that. The below does NOT include these, so let me know if you'd like usb-devices with all peripherals plugged in.
