Subject: AC 8265: Microcode SW error detected. Restarting 0x82000000.
Dear Linux folks,
Building Linux 6.10-rc2 myself with the attached config,
$ grep IWLW /boot/config-6.10.0-rc2
CONFIG_IWLWIFI=m
CONFIG_IWLWIFI_LEDS=y
CONFIG_IWLWIFI_OPMODE_MODULAR=y
# CONFIG_IWLWIFI_DEBUG is not set
CONFIG_IWLWIFI_DEVICE_TRACING=y
and booting it on a Dell XPS 13 9370, I get the errors below. Using
Debian’s linux-image-6.8.12-amd64, these errors do *not* occur.
