Package: firmware-iwlwifi Version: 20190717-2 Followup-For: Bug #934781 I did some further digging - in my case, at least, the problem seems to be triggered by some relatively recent kernel change. I combed through the system journal for the last few months, and the problem first starts appearing in the logs a few days after I began running kernel 5.2.x (from 5.2.7 through 5.2.9). Previously, while running 4.19.x, the problem never appears.
I haven't done a bisection, but it seems pretty clear at this point that there's a microcode bug that has begun to be triggered by something in newer kernels. -- System Information: Debian Release: bullseye/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.19.0-5-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.
