Bug#939262: firmware-iwlwifi: Consider update to newest version (20190815)
See my report in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=934781#30 On my Dell Precision M6400 laptop, the newer iwlwifi 20190815 firmware only partly fixes the problem. The Wi-Fi no longer hangs (great!), but Microcode SW errors still occur in periods of high throughput. -- System Information: Debian Release: bullseye/sid APT prefers testing APT policy: (990, 'testing'), (500, 'xenial-security'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.3.0-2-amd64 (SMP w/2 CPU cores) Kernel taint flags: TAINT_FIRMWARE_WORKAROUND Locale: LANG=en_AU.UTF8, LC_CTYPE=en_AU.UTF8 (charmap=UTF-8), LANGUAGE=en_AU:en (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.

Bug#934781: firmware-iwlwifi: iwl4965: Microcode SW error detected
As an experiment, I downloaded the tarball from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tag/?h=20190815 (as recommended in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=939262 ), and manually copied its intel/* and iwlwifi-* files into /lib/firmware (overwriting the ones installed by the firmware-iwlwifi package). After rebooting kernel 5.3.0-2 (amd64) I still get "iwlwifi: Microcode SW error" messages accompanied by "ieee80211 phy0: Hardware restart was requested" during periods of high Wi-Fi throughput, but they do not cause the Wi-Fi to hang. So the newer firmware appears to rectify the worst part of the problem (Wi-Fi freeze) but does not fully resolve the problem.

Bug#946601: linux-image-4.19.0-6-amd64: High load by kworker, shutdown or reboot hangs
Hi all, I would like to add a detail: I checked today: on shutdown, the system hangs for at least 3 hours with the message watchdog: watchdog0: watchdog did not stop! This means: the machine did not reboot, I had to switch off the machine manually. I would therefore suggest to increase the severity. I stored the complete dmesg output and can provide if wanted.

This is always related to the increased load and the respective dmesg messages. I experienced this behaviour about 20 times within the last few months. I did not find any workaround t solve this situation. Cheers, Olaf
