Package: src:linux Version: 4.18.20-2 Severity: normal Tags: patch Hi!
After kernel 4.17 the dtb for raspberry pi 3 b is not ok and thus the wifi is not found and cannot be used. Looking at the differences from 4.17 to 4.18 I have discovered that if you revert this single patch affecting only the pi3b model the wifi is discovered and works again. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/arch/arm/boot/dts/bcm2837-rpi-3-b.dts?id=b1b8f45b3130dbd8704e5ea0d82b49b1d929498e I have tested this both on Linus kernel 4.20-rc5 and on Debian 4.19.5 as currently on experimental, on both reverting this patch makes the wifi work again.
