Basically out of nowhere (it would seem),
sys-net as a USB Qube seems to suddenly spike once it’s been left open after several days (7 days, I think….)
This is where it gets weird:
- Fans spin up all of a sudden and stay constantly on.
- Any USB HID devices “stutter” (the cursor moves around the screen, similar to watching a movie with dropped frames, that’s the best way I can describe it…)
sys-usbsays that everything is normal, and CPU usage is at 5%
- The process with the highest usage seems to be
- It should be noted that
systemd-journaldis the next-highest process
xl topin dom0 says that CPU usage is ~50%
- After this happening a few times over the past couple of weeks, I got curious and left the machine on overnight this time, to see whether it would sort itself out. The fans were still continuously running at the same speed in the morning, with the same reported CPU usage.
qvm-kill sys-usb; sleep 10; qvm-start sys-usbseems to fix it (disposable VM)
Whilst I have already discovered a “fix” (a very hacky fix…), my intention is to assist in finding the part of the codebase that is causing this, to assist the devs.
I’m happy to provide any machine info and/or logs (it is a testing machine, after all), but I honestly have no idea where to start….
