I have my logs filled with similar garbage throughout 5.3-rc*. Also
since 5.3-rcsomething not only it WARNS in dmesg about firmware failure,
but completely stops working after suspend/resume cycle.

It looks like that:

commit 4fd445a2c855bbcab81fbe06d110e78dbd974a5b
Author: Haim Dreyfuss <>
Date: Thu May 2 11:45:02 2019 +0300

iwlwifi: mvm: Add log information about SAR status

Inform users when SAR status is changing.

is the culprit. (manually) reverting it on top of 5.3-rc4 makes
everything work again.
