Do you mean 831fe284d8275987596b7d640518dddba5735f61 has this regression? Can you also pinpoint the culprit by doing bisection?

Hi Bagas, issue is present in both 6.5.0-rc1 (with johannes’s patch) and 831fe284d8275987596b7d640518dddba5735f61. I have been testing head, as the iwlwifi patch https://lore.kernel.org/linux-wireless/20230710145038.84186-2-johannes@sipsolutions.net/ was needed on my system.

I haven’t attempted a bisect on this.

Can you also try Ilan's patch [1]?

I can confirm https://lore.kernel.org/regressions/ZLZHDm3mcxaLdvRH@503599e9be06/  that the patch in https://lore.kernel.org/regressions/DM4PR11MB6043088A4A65CBF124F5D518E93BA@DM4PR11MB6043.namprd11.prod.outlook.com/ fixes the error.
