I don't know if it's a kernel bug or a problem in systemd-247 but it
didn't happen with kernel 5.10.16.
Hi John,
The issue is due to the kernel developers changing the 'rfkill' API in
5.11.0 and breaking compatibility as a result.
Try applying the changes in
https://github.com/systemd/systemd/commit/e133c454b1beda0d80020a35f9f92226e8167bc1
to your system and let us know if that works.
Here's the relevant commit from the kernel:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=14486c82612a177cb910980c70ba900827ca0894
And the systemd bug report: https://github.com/systemd/systemd/issues/18677
Thank you for bringing it up!
- Doug
