Hi.

First of all, thanks for the detailed instructions. Response inline.


sure thing!

    -- pay special attention to the update the /boot/loader.conf


Are you referring to the need to set 'hw.sysconf.disable=1', or is there something else I'm missing? I didn't see anything else on the wiki page, except for some debugging options (which I guess I'm going to end up using soon).

yes that is what i was referring to.  I do not have an AMDGPU system myself but have been told several times that it is required.


    - after you have configured the amdgpu.ko to load on boot verify
    it is
    able to load the kernel module and your console display looks
    good.  if
    you have issues loading the kernel module let us know, there are some
    things you can try to setup to get a useful backtrace that will
    help us
    debug this.


This is where I get to. I've removed amdgpu from /etc/rc.conf, so I don't have to boot single-user mode; when I run kldload amdgpu, the following happens:

1: the 'kldload amdgpu' process doesn't return immediately, yet the terminal is responsive; I can hit return, and have the cursor move. The mouse pointer also moves. 2: something around 5s later, the screen turns off, the keyboard goes unresponsive (caps lock light doesn't toggle), and the machine no longer responds to pings.


interesting, it looks like the kernel module and firmware modules do load.  one thing you may want to test is setting the "debug.debugger_on_panic=0" sysctl knob before loading the amdgpu.ko.  hopefully this will allow you to get into a debugger before the system locks up.

cheers,
-pete
