Re: kernel 5.2.x and firmware-iwlwifi: incompatibilities?

[Miguel A. Vallejo]

Actually runing linux-image-4.19.0-5-amd64 (4.19.37-6) without any
wifi issues (this is a desktop), but with linux-image-5.2.0-2-amd64
wifi is unstable with too frequent drops.

WiFi card is a MediaTek MT-7612 USB dongle.

Hope this helps

Migual has you update to 4.19.37-5+deb10u1 ?

With previews version of 4.19 I had problems after suspend to disk.
Now it seems to be fixed.

There are several Bug Reports with "iwlwifi 4.19 suspend" when you
search in on google.

Best Regards

Same problem here. Kernel 5.2.x makes my MT76x2 wifi very unstable,
with bad performance and lot of dropouts. Running 4.19.x for now.

kernel 5.2.x and firmware-iwlwifi: incompatibilities?

[Patrice Duroux]

Hi,

I am using Sid on my laptop (HP ZBook 15) and since first
linux-image-5.2.0-1 and then linux-image-5.2.0-2
the wifi is not stable and goes down after few seconds.
But what is more strange is that with linux-image-5.2.0-1 there is a log
trace of the trouble but not with linux-image-5.2.0-2.

Here is an extract of the log using first package 5.2.0-1:
