I will also post this information on the bug. We cannot break user space like that, linux-firmware needs to be backwards compatible. In other words, anything you submit to linux-firmware needs to work with old kernels. Should this new firmware be reverted from linux-firmware? What about changes in the rtw89 driver? Do they still work with old firmware? -- https://patchwork.kernel.org/project/linux-wireless/list/ https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches
