Attaching full dmesg from next boot. Several iwlwifi traces in there which look different.

Comment 2 Thomas Backlund 2019-10-24 22:08:15 CEST

Yeah, Intel really screwed up when they backported SAR support to current stable api firmwares, and they have been fixing up the fallout ever since...

I've just added the fix for this in kernel-5.3.7-4.mga7 currently building...

Comment 3 claire robinson 2019-10-24 22:11:23 CEST

Thanks Thomas, will try it tomorrow.

Comment 4 Thomas Backlund 2019-10-25 21:14:23 CEST

kernel-5.3.7-4.mga7 is now mirroring out

Depends on: (none) => 25602

Comment 5 claire robinson 2019-10-26 00:01:14 CEST

Still waiting for the mirror to sync fully. It says it has it but is telling fibs. Will test it in the morning, worst case.

Comment 6 claire robinson 2019-10-26 11:25:16 CEST

Confirmed good fix Thomas, thank you.

Comment 7 Thomas Backlund 2019-10-29 16:09:08 CET
