Hi, I recently bought a used ThinkPad X13 1st Generation. That one is equipped with an: 00:14.3 Network controller [0280]: Intel Corporation Comet Lake PCH-LP CNVi WiFi[8086:02f0] (lspci output avaible online as https://www.zugschlus.de/stuff/lspci-v and https://www.zugschlus.de/stuff/lspci-nn) I can reproduce the following behavior with all Linux kernels beginning with the one that is in Debian Stable (didn't try anything older than that), Debian unstable, current Linux Mint, Fedora Workstation 41, up to a self-compiled Linux 6.12.5). While there was a Windows installed on the box when I got it, I do not intend to dual boot the machine, and Windows has been erased by installing the first Linux over it. Hence, I dont consider the hints found on the Internet regarding Windows fast startup applicable in my case. In any case, I disabled Windows fast startup before overwriting Windows. When the notebook is freshly cold booted (machine OFF, no led blinking, pulsing or anything, power supply disconnected), Wifi works. When I just reboot the machine without turning it actually off, or turn it off while leaving the power supply connected, Wifi does not work. The Wifi chip still shows up in lspci but not in ip addr / ip link. dmesg looks like it does not even try uploading firmware. In the non-working case, I see a bunch of lines like [ 3.998476] iwlwifi 0000:00:14.3: CSR_RESET = 0x10 [ 3.998494] iwlwifi 0000:00:14.3: Host monitor block 0x0 vector 0x0 [ 3.998524] iwlwifi 0000:00:14.3: value [iter 0]: 0x00000000 [ 3.998545] iwlwifi 0000:00:14.3: value [iter 1]: 0x00000000 [ 3.998566] iwlwifi 0000:00:14.3: value [iter 2]: 0x00000000 [ 3.998587] iwlwifi 0000:00:14.3: value [iter 3]: 0x00000000 [ 3.998608] iwlwifi 0000:00:14.3: value [iter 4]: 0x00000000 ending with [ 4.007732] iwlwifi 0000:00:14.3: probe with driver iwlwifi failed with error -110 (full output on https://www.zugschlus.de/stuff/dmesg-notwork) For reference, see dmesg output for a working case on https://www.zugschlus.de/stuff/dmesg-work. As per the instructions given on https://wireless.docs.kernel.org/en/latest/en/users/drivers/iwlwifi/debugging.html, I have not yet upped the debug level. I am prepared to try with a kernel that has CONFIG_IWLWIFI_DEVICE_TRACING and/or CONFIG_IWLWIFI_DEBUG set. If you ask me to do this, please give me instructions about how to enable the desired debugging if module parameters, kernel command line parameters etc are necessary. I would apprecaite any help. I can keep the machine in the current state for a few days, I only need it after chrismas. Please keep me on Cc, I am not subscribed to the mailing lists.
