Package: linux-image-5.10.0-8-amd64 Version: 5.10.46-2 Severity: important Hi,
I just successfully installed the latest version of Debian testing bullseye on a brand new Dell XPS 15, but I got some issues with the integrated WiFi card. Of course I installed the non-free firmware. The Linux image package is linux-image-5.10.0-8-amd64, version 5.10.46-2. Here is the log (grepped for iwlwifi): [ 14.352938] iwlwifi 0000:00:14.3: enabling device (0000 -> 0002) [ 14.358907] iwlwifi: No config found for PCI dev 43f0/1651, rev=0x354, rfid=0x10a100 [ 14.368948] iwlwifi: probe of 0000:00:14.3 failed with error -22 Then I tried to install the latest kernel version (5.13.6), I built it and installed, and now the WiFi card works just fine ! Here is the log of the working kernel: [ 67.899239] iwlwifi 0000:00:14.3: enabling device (0000 -> 0002) [ 67.901544] iwlwifi 0000:00:14.3: Direct firmware load for iwlwifi-QuZ-a0-hr-b0-63.ucode failed with error -2 [ 67.903867] iwlwifi 0000:00:14.3: api flags index 2 larger than supported by driver [ 67.904108] iwlwifi 0000:00:14.3: TLV_FW_FSEQ_VERSION: FSEQ Version: 89.3.35.37 [ 67.904350] iwlwifi 0000:00:14.3: loaded firmware version 62.49eeb572.0 QuZ-a0-hr-b0-62.ucode op_mode iwlmvm [ 67.916597] iwlwifi 0000:00:14.3: Detected Intel(R) Wi-Fi 6 AX203, REV=0x354 [ 68.104800] iwlwifi 0000:00:14.3: base HW address: 4c:79:6e:d9:d7:c1 [ 68.649015] iwlwifi 0000:00:14.3 wlp0s20f3: renamed from wlan0 According to Dell, it's supposed to be "Killer Wi-Fi 6 AX1650 (2x2)" but it looks like the linux kernel doesn't agree. While looking at this problem, I found some strange issues. It looks like that that the lines for this device were in the kernel but were removed in [1]. I believe that v5.10 includes this change. Could a simple fix be as simple as adding these lines back? I'l not understanding this change properly.

Please ask any more information if needed. Thanks! -- Julien
