Could you give hwinfo output?
Done

There is nothing serious shown in the kernel itself, so it's hard to judge only from the current log, unfortunately.
How can I get more information if this happens again? (fortunately, this does not happen often) Perhaps with the 5.16 kernel it will be fixed

What is the a.out at the end of the log? There seems to be lots of segfaults happening there (the suppressed show_signal_msg).
Its buggy application (there off-by-one bug) I think problem in iwlwifi driver
Possible. But usually WiFi driver problem shouldn't bring such a slowdown.
Is the slowdown phenomenon reproducible? I wonder whether it was due to the massive crashes (segfaults) of buggy application you mentioned in the above. Since each crash triggers the core dump and processing via systemd-coredump, it'll take lots of CPU and storage resources.
fortunately, I haven't noticed such problems lately, but I don't use a Bluetooth keyboard and headphones right now people on the forums wrote that there was a similar problem when using Bluetooth and 5 GHz wifi now the system hangs only from the firefox browser on some sites, but this is more of a browser problem (everything is fine on chromium) but if there is a way to debug, then I am ready to try to catch a similar state again -- You are receiving this mail because: You are the assignee for the bug.
