Hey Arend I recently bisected a user-reported WiFi breakage on the Raspberry Pi 3B+ to your commit https://github.com/torvalds/linux/commit/d6a5c562214f26e442c8ec3ff1e28e16675d1bcf https://lore.kernel.org/r/20221129135446.151065-4-arend.vanspriel@xxxxxxxxxxxx On our end, the issue was reported here: https://github.com/gokrazy/wifi/issues/3 As of Linux 6.2.6, this seems to still be unfixed, so I wanted to check in and see if you could take a look please? Thank you. Here’s a dmesg diff between the previous commit (da6d9c8ecd00) and the broken commit (d6a5c562214f): --- /proc/self/fd/11 2023-03-14 20:28:20.167241380 +0100 +++ /proc/self/fd/12 2023-03-14 20:28:20.167241380 +0100 @@ -1,5 +1,5 @@ Booting Linux on physical CPU 0x0000000000 [0x410fd034] - Linux version 6.1.0-rc7-01766-gda6d9c8ecd00 (gokrazy@docker) (aarch64-linux-gnu-gcc (GCC) 12.2.0, GNU ld (GNU Binutils) 2.39) #81 SMP PREEMPT Wed Mar 1 20:57:29 UTC 2017 + Linux version 6.1.0-rc7-01767-gd6a5c562214f (gokrazy@docker) (aarch64-linux-gnu-gcc (GCC) 12.2.0, GNU ld (GNU Binutils) 2.39) #82 SMP PREEMPT Wed Mar 1 20:57:29 UTC 2017 random: crng init done Machine model: Raspberry Pi 3 Model B Plus Rev 1.3 efi: UEFI not found. @@ -29,7 +29,7 @@ Fallback order for Node 0: 0 Built 1 zonelists, mobility grouping on.
