Bug#915808: Current dtb for raspberry pi 3b doesn't allow wifi to be used
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.

Bug#856505: This patch should solve the audio problem
Hi!
Based on eHenry's instructions I have created this patch which I have tested
on Debian's 4.19 kernel now on experimental, where we have already enabled
the sound driver which was not working.
The result is that with this patch the sound is finally working, so, please
apply this to the 4.19 kernel to enable sound.

FWIW, I have now verified that reverting commit 06e562e7f515
("drm/i915/ringbuffer: Delay after EMIT_INVALIDATE for gen4/gen5") fixes
this issue for me.

Bug#856505: Sound working on the pi3b with eHenry's patch
I've compiled a Debian 4.19 kernel with your sugested patch to enable audio and reverting another one to fix the WiFi problem and I now have both audio and WiFi working. I'll send proper patches as soon as I have time, but it works. Regards. -- Santiago García Mantiñán
