Is your firmware up to date? Could you update it to the latest git master version and check again? Secondly, is this a regression? Do any previous kernels work without errors? > Is your firmware up to date? Could you update it to the latest git master > version and check again? Hmm, I updated a few hours ago up to e068ccf0 and for now haven't seen an error. Will test for some more, let's see if errors are gone. > Secondly, is this a regression? Do any previous kernels work without errors? I noticed errors on 6.7 kernel version; whether they were on older kernels I don't know offhand.

Will test for some more, let's see if errors are gone. Problem is still present. It looks like the updated FW made it happen much more rarely (but it may be a coincidence). In the log attached initially it can be seen to have been happening every ≈½ an hour or so. But right now for 14.5 hours it happened just twice. That said, the error trace is exactly the same (compared side-by-side in vimdiff), so it's still happening. Turns out this does cause problems. If stack appears and music plays, that music lags. Any news on this? Emmanuel, hello, why you closed this bug as "obsolete"? I should have added a comment. Please re-open if still relevant. I closed this bug as part of a bulk cleanup. Reopning as the problem still persists on kernel 6.14.4 Sorry it took so long to re-check, it turns out I found a workaround which I was using all that time. Basically, the problems happens if you set "channel width" in router settings to 40Mh. This then results in WiFi card attempting to change channels (see the starting messages), and then from what I understand driver crashes? Causing the network connection to restart. The problem doesn't happen if "channel width" is set to 20mh. Can you please share a recent log? Created attachment 308138 [details] 6.14.4 journalctl log of the bug (In reply to Emmanuel Grumbach from comment #8) > Can you please share a recent log? Sure, attaching. I should note that the latest log says "tainted" because I have NVidia driver loaded right now, Nouveau often freezes with multiple monitors. I really-really tried sticking with Nouveau (I'm not even a gamer), but this is just not working out. This is unrelated to the report, because my original log which is ± the same was done on the "non-tainted" kernel, you can see it say "Not tainted" there. Thanks. This is a driver bug. Is it easy to reproduce? If yes, I'd like to ask you to record tracing: sudo trace-cmd -e mac80211 -e cfg80211 -e iwlwifi Created attachment 308139 [details] `trace-cmd record -e mac80211 -e cfg80211 -e iwlwifi` trace during the problem (In reply to Emmanuel Grumbach from comment #11) > Thanks. > This is a driver bug. > > Is it easy to reproduce? > If yes, I'd like to ask you to record tracing: > > sudo trace-cmd -e mac80211 -e cfg80211 -e iwlwifi Thank you, attaching. I reconfigured router to 40mh, manually reconnected to the WiFi, and then launched the tracing command. Created attachment 308140 [details]
the log that was happening during the tracing
And attaching the log that was appearing while the tracing was working.

Created attachment 306029 [details] `journalctl -b` output for the boot that goes \w the report Occasionally I'm getting `FW error in SYNC CMD PHY_CONTEXT_CMD` error in the log along with stacktrace. I'm not doing anything in particular at that moment, it just happens on its own, often. On previous 6.7.9 kernel version I also sometimes had system crash, I'm not sure if it's because of this or not. On my current 6.8.1 I did not have that happen (yet).
