    I'm experiencing this bug too, looks like i915 has been changed/updated to include the new xe driver and it's broken.

    dmesg:
    [ 2.740670] xe 0000:01:00.0: Your graphics device 56a6 is not officially supported
    by xe driver in this kernel version. To force Xe probe,
    use xe.force_probe='56a6' and i915.force_probe='!56a6'
    module parameters or CONFIG_DRM_XE_FORCE_PROBE='56a6' and
    CONFIG_DRM_I915_FORCE_PROBE='!56a6' configuration options.

    $ intel_gpu_top
    No device filter specified and no discrete/integrated i915 devices found

    $ lspci | grep DG2
    01:00.0 VGA compatible controller: Intel Corporation DG2 [Arc A310] (rev 05) 02:00.0 Audio device: Intel Corporation DG2 Audio Controller

    blacklisting the xe module makes the dmesg error go away but the gpu still isn't available for use. My GPU is an Intel Arc A310.

    Hi,

    I found that this condition happened from the upstream kernel. I checked kernel 6.12.35 ~ 6.12.40, they all had the same issues.

    Maybe we can only wait until upstream fixes or upgrade to kernel-6.15.

    Debian 13 is about to be released, shipping with the 6.12 kernel. Unfortunately, after installation, it was found that the Intel B580
    graphics card is not supported, which is quite a pity.

    Can you bisect the changes between 6.12.33 and 6.12.35 upstream to
    identify the breaking commit and report it back here?

    Regards,
    Salvatore
