Hi Thorsten, Sorry, missed this report. Let me read and respond. Thanks, Golan. -----Original Message----- From: Linux regression tracking (Thorsten Leemhuis) <regressions@xxxxxxxxxxxxx> Sent: Wednesday, June 14, 2023 18:49 To: Greenman, Gregory <gregory.greenman@xxxxxxxxx>; evgeny nikiforov <evgeny.niki4off@xxxxxxxxx> Cc: Linux regressions mailing list <regressions@xxxxxxxxxxxxxxx>; linux-wireless@xxxxxxxxxxxxxxx; stable@xxxxxxxxxxxxxxx; Ben Ami, Golan <golan.ben.ami@xxxxxxxxx> Subject: Re: [iwlwifi] 6.3 regression, AX201 crash on traffic activity with Pixel 7, bisected On 05.06.23 22:12, evgeny nikiforov wrote: > bisecting results in following: > crash behavior happened on this commit with switch fw from 72 to 74: > linux 6.3: 9ad1e7e5b0c488e4518edd698238a87ac6a73caa wifi: iwlwifi: > bump FW API to 74 for AX devices > crash not reproduced after this commit on switch fw from 75 to 77: > linux 6.4: ef3ed33dfc8f0f1c81ca103e6b68b4f77ee0ab65 wifi: iwlwifi: > bump FW API to 77 for AX devices Thx for this, but I guess that sadly doesn't bring us any closer, as those commits likely hide the real culprit/fix. Sadly the Intel wireless developer seem to ignore this report. That is really unfortunate. :-( I wonder if I should escalate this to higher authorities. But OTOH: 6.3 will be EOL in about a month anyway, so maybe that's not worth it. Evgeny, what do you think? Are you maybe willing to run 6.4-rc now and ignore this, as this apparently is an issue that only bothers you?
