Created attachment 286205 [details] dmesg output from a cold boot on 5.4.2 Hello linuxwifi@intel.com and iwlwifi team, The firmware for my Wireless-AC 9560 seems to fail to start. It happens on 5.4.1 and 5.4.2, but it's fine on 5.3 and before. It also tries on a loop every second or so, flooding syslog with call trace, and incrementing the id of the interface in `ip addr` and `rfkill` for the short interval of time it appears in them. I would provide a dev coredump but there isn't any, which seems to relate to the line "Firmware not running - cannot dump error" in syslog. Maybe my configuration is to blame since `/sys/devices/virtual/devcoredump/` does not exists, but they are correctly created with the udev rule on 5.3 so I don't know for sure. I only found one occurrence of a similar issue in the wild: https://forum.manjaro.org/t/unsure-what-wifi-driver-to-install-for-huawei-laptop/112351 (this is my first bug report here, please tell me if I did something wrong)
Created attachment 286207 [details] ethtool -i wlo1 The output is the same on 5.3 besides the kernel version being 5.3.13-arch1-1
Created attachment 286209 [details] lspci -s 00:14.3 -xxxvvv on 5.3.13
I have the same card and the same problem.
Not sure how nor when, but it seems to be fixed, at least in 5.5.6. Closing to keep it clean.
