@linrunner: Thanks for the explanation that tlp will mostly work without acpi-call-dkms and completely without it in the future! Also your warning hint from the TLP doc might help some people here:
"Warning: On Ubuntu 21.10 and 20.04.4 the acpi-call-dkms packages in the official repositories are incompatible with the provided kernel 5.13 and may cause TLP battery care malfunction, system freezes and reboots. Solution: use acpi-call-dkms version 1.2.2 from the TLP PPA or download from Ubuntu 22.04 and install manually." – https://linrunner.de/tlp/installation/ubuntu.html#thinkpads-only @raph: Still this package is not fixed for Ubuntu 20.04 and could render more laptops unbootable. The bug status „Fix released“ is not true for 20.04. Could someone maybe adjust the bug status? Could you provide some insight what's holding you back to get the fix into Ubuntu 20.04? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1953261 Title: kernel >= 5.13 BUG: kernel NULL pointer dereference To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/acpi-call/+bug/1953261/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
