This bug is affecting me too on Ubuntu 20.04 on a Macbook Pro 15". Took me several installations and quite some hours to figure out, what the reason for misbehaving and overheating was, should have launched top right away.
For me the workaround with suspending after boot works fine, too. But it is also kind of annoying to suspend once after booting the computer. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1878919 Title: kworker/0:1+kacpid uses 100% of one CPU core To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1878919/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
