I started receiving this warning message during startup. This computer has worked without issue for several months. It still functions, however I want to learn more about this warning.
It occurs right before I enter my password to decrypt my LVM partitions. I'm using LVM on LUKS per the wiki. I've searched each term after the <TASK> line on the wiki and in a few search engines without finding anything I quite understand. Can anyone guide me to resources to learn more about this warning?

Then there's a lot of letters and numbers that look like hex values, followed by:

Thank you.
I tried locating kernel/trace/trace_events.c but failed. Also tried using find for trace_events.c as well, but got nothing. I’m trying to learn and wanted to read line 577 from the error. Where do I find the trace_events file?

Edit:
https://github.com/archlinux/linux/comm … 293f4b626f is the fix which is part of v6.12.9-arch1 which is due to be the next release of the linux package.
