Bug#941946: resolution

2019-10-11 Thread Peter Upton
Bug no longer occurs after BIOS update.
Looks like this was a bug with the bios and not Debian.


Bug#941946: linux-image-5.2.0-0.bpo.2-amd64: kernel oops and system freeze after installing firmware-iwlwifi

2019-10-07 Thread Peter Upton
Package: src:linux
Version: 5.2.9-2~bpo10+1
Severity: important
Tags: upstream

Dear Maintainer,

While running kernel 5.2.0-0.bpo.2-amd64 with firmware-iwlwifi
installed, system freezes and becomes non-responsive to any user input.
Freezing occurs shortly after boot with no warning.

Below are possibly relevent lines from /var/log/messages logged when the system
froze:
