Hi, Thorsten here, the Linux kernel's regression tracker.
mt7921 maintainers, I noticed a report about a regression in bugzilla.kernel.org related to your driver. As many (most?) kernel developers don't keep an eye on bugzilla, I decided to write this mail. To quote from https://bugzilla.kernel.org/show_bug.cgi?id=218731 :
> On kernel 6.6.27-1-lts, running `iw list` shows that 6GHz channels are supported:> > [...] > Similarly, discovering and connecting to 6GHz APs works fine. > > However, in recent kernel 6.8.5, running `iw list` shows that 6GHz channels are disabled: > > [...] > > And scanning or connecting to 6GHz APs does not work. > > There's nothing in `dmesg` that differs between boots of the two kernels. On 6.8.5, 6GHz band doesn't work like it did on previous kernels. > > I can provide more logs or help debug the issue if needed.
See the ticket for more details. Note, you have to use bugzilla to reach the reporter, as I sadly[1] can not CCed them in mails like this.
Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) -- Everything you wanna know about Linux kernel regression tracking: https://linux-regtracking.leemhuis.info/about/#tldr If I did something stupid, please tell me, as explained on that page.
[1] because bugzilla.kernel.org tells users upon registration their "email address will never be displayed to logged out users"
P.S.: let me use this mail to also add the report to the list of tracked regressions to ensure it's doesn't fall through the cracks:
#regzbot introduced: v6.6..v6.8.5 #regzbot title: wifi drivers: mt7921: 6GHz band stopped working #regzbot from: AlexDeLorenzo.dev #regzbot duplicate: https://bugzilla.kernel.org/show_bug.cgi?id=218731 #regzbot ignore-activity
