    Both kernels are stock kernels from kernel.org (though I did add the
    BMAC patch to 5.6.13). I can send the .config files that I used if that
    would be helpful. I have the same options in both .config files for
    "Device Drivers -> Graphics support -> Frame buffer devices", with "Open Firmware frame buffer device support" and "ATI Rage128 display support" selected (among other options).

    I'm pretty sure that rather than FB_ATY128 ("ATI Rage128 display support")
    you would need FB_ATY ("ATI Mach64 display support") for that model.
    That's what I remember from the last time I booted mine up. I have a
    roughly equivalent model. However, I haven't tried a new kernel on
    mine in quite some time. There have been complaints on the list in
    recent years about various parts of the ATI mach64 support being broken.

    Hello Stan,

    We had the same issue during the 5.14 merge window. Please look in the following thread:

    https://forum.hyperion-entertainment.com/viewtopic.php?p=53511#p53511

    There is a patch available. Please try it.

    Thanks,
    Christian

    While attempting to upgrade the kernel from 5.6.13 to 5.13.2, I'm having trouble getting X to work. The symptoms are that in 5.13.2, the screen
    goes blank and never comes back. Since the network and disk access were
    ok, I was able to login and noticed that wdm is running. The Xorg.0.log
    files in /var/log are essentially the same for both kernels; I can send
    those log files if someone might find them useful (I didn't want to send large files to the entire list).

    The framebuffer is reported as "fb0: Open Firmware frame buffer device
    on /pci/ATY,RageLTPro". I tried adding "mach64" to the config file for 5.13.2, but that didn't fix the problem.

    Graphics (Xorg, wdm and xfce) work in Debian 7.8 with kernel 5.13.2. So
    I'm not sure whether I'm looking for a kernel issue or an Xorg (or wdm) issue, so I haven't run a git bisect yet.

    thanks for any suggestions
