Hi,
I just upgraded my laptop (Lenovo T470p) to latest TW 20210820, including kernel 5.13.12.
Now I have a permanent kworker process running at full load:
27615 root 20 0 0 0 0 R 99.00 0.000 5:49.23 kworker/u16:3+events_unbound
I encountered this issue last week and again today.
11663 root 20 0 0 0 0 R 100.0 0.000 20:41.19 kworker/u16:0+events_unbound
Is there a way to find out what exactly it is related with?
Time to reboot before something becomes toast...

This happened to me about a two months ago, then again a few weeks ago. For me, this was btrfs doing strange things. My laptop is also a Lenovo (Thinkpad T580) A reboot fixed it for an hour or so, but a rebalance seemed to fix it completely each time. I seemed to coincide with when I run my firefox container under docker (old Firefox with Flash and Java), so I thought it may be an issue with the docker plugin causing a lot of BTRFS activity and the kernel doing.. something. My filesystem is not super full, but it is on a Samsung 970 PRO NVMe so the CPU will get a little smashed with the data throughput when background 'stuff' happens which is only I/O limited. It does not happen every time, but it never seems to happen any other time for me. Either way, a rebalnce stopped it and it went away. The fan on my laptop gets very annoying otherwise. Not sure if this correlates with anything anyone else is seeing. Unfortunately, I do not have anywhere near enough information to actually file a quarter decent bug report, but I can confirm this has been happening since at least 5.12.x and it seems to also be plastered across the Fedora mailing list as well (but once again, nobody gathering enough information for a real bug report). Always that same events_unbound. -- Ben
