libreelec nightly regression on amd 2400g

  • With the latest (20201015-c5a4c7d) nightly I'm seeing a regression as it seems to fail to init the gpu on my AMD 2400G, so the box just boots and kodi does not start up, I can ssh into it though.

    Relevant stuff from dmesg:

    non-working - Pastebin

    The nightly (20200928-cf4721a) I used previously works:

    working - Pastebin

    Let me know if you need anything else.

    As it's not really my department, the nightly problem is to be looked at by a LibreELEC developer.

  • So I did a git bisect and got this:

    addc2bfa1f3cbd6f876f4b98dac71f33d01cf837 is the first bad commit
    commit addc2bfa1f3cbd6f876f4b98dac71f33d01cf837

    linux: add IOMMU support for Generic

    Reverting this commit on master and my box boots fine again.

  • I tested again, I've had "pci=nomsi" for a long time. I think it was milhouse that suggested that for boot problems with this platform. So I tested removing that and now it boots without the "iommu=off".
