• Bug#1108324: linux-image-6.15-rt-amd64: i915 module nonexistent (1/6)

    Version: 6.15.3-1~exp1
    Severity: important
    X-Debbugs-Cc: hueychen27@outlook.com

    Dear Maintainer,

    For some reason, this specific version, 6.15-rt-amd64, does not include the i915 driver, so we are forced to use the experimental (and maybe buggy) xe driver. 6.15-amd64 does have the i915 driver; I am not sure why that was not included with this version.
    Searching with `apt-file search i915.ko.xz | grep linux-image-` shows that `linux-image-6.15-rt-amd64` does not appear, but `linux-image-6.15-amd64` does.

    Sincerely,
    Huey Chen

    i915 simply does not work with the RT settings enabled. There are
    patches somewhere, but they have deliberatelly not merged yet.
