If you’d rather not, I can keep a note on my TODO for when the other system is back up, then reproduce and either unarchive or let it rest, as I don’t have a timeframe for that. bye, //mirabilos -- [16:04:33] bkix: "veni vidi violini" [16:04:45] bkix: "ich kam, sah und vergeigte"...

I'm also having this issue. LG Gram 17 2019 Intel Wireless-AC 9560 Running testing (Debian GNU/Linux bullseye/sid) Under the current kernel (linux-image-5.10.0-6-amd64) the Wifi was bugging out constantly, making it almost unusable. (No ethernet port on the machine!) I tried all versions of the firmware (by renaming the files in /lib/firmware/iwlwifi-9000-*) none were noticeably better. I downgraded to linux-image-4.19.0-16-amd64 (firmware v38), and thought it was solved, but it's still happening intermittently.

On my system, the problem last appeared on Sep. 17 (with a Debian kernel version 5.2.9-2). Since then, I have not seen any "Microcode SW" errors. I've been running 4.19.72 (self-built), 5.2.17-1, 5.3.7-1, 5.3.9 (-1, -2, -3), and 5.3.15-1 (Debian).

Bug#934781: firmware-iwlwifi: iwl4965: Microcode SW error detected
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.

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.

I'm experiencing a similar problem with 8265 and kernel 5.2.7 -- I got the microcode sw error today, and my wifi has been reconnecting very often lately. And I even got a "kernel: list_del corruption", which may be unrelated, but all the reconnecting probably makes it easier to trigger. Anyway...
