Package: firmware-iwlwifi Version: 20190717-2 Followup-For: Bug #934781 Hi,
I'm also seeing Microcode SW errors on my Sid system (see attached). I'm not sure when they started, but I do look at my logs fairly often, and I've never noticed them before. Sometimes performance is not affected, but sometimes I see throughput drop from about 240-260 Mbps to about 30-40 Mbps. ~$ uname -a Linux lila 5.2.0-2-amd64 #1 SMP Debian 5.2.9-2 (2019-08-21) x86_64 GNU/Linux ~$ lspci | grep Wireless 03:00.0 Network controller: Intel Corporation Wireless 7265 (rev 99) -- System Information: Debian Release: bullseye/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.2.0-2-amd64 (SMP w/4 CPU cores) Kernel taint flags: TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.utf8, LC_CTYPE=en_US.utf8 (charmap=UTF-8), LANGUAGE=en_US.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled firmware-iwlwifi depends on no packages. firmware-iwlwifi recommends no packages.
