I managed to get a panic dump from my -current amd64 host with a
FireGL card using DRMKMS. Dmesg, gdb trace and Xorg.0.log attached (if
one starts only Xorg, it kinda works - a functional cursor is seen
with a small white rectangle at the top left corner; anything more

The good news is that DRMKMS doesn't crash any more on boot on that
machine; Xorg shows the cursor in the screen centre and a small white
rectangle in the top left corner; the machine is reachable from
outside, but the console is unresponsive from this moment on; if I try
something further (like

Now it panics (and rebuilt the X server with symbols just in case):
It (radeon) no longer panics!

I get a panic in a call to munmap(2) but that may just be happening when
the server is cleaning up from some other error.
There is a bug somewhere in the establishment of VM

On i386, the ioctl() of DRM_RADEON_GEM_MMAP is returning addresses
above 4GB which obviously cause drmMap() of them to fail.
This isn't obvious to me -- off_t is 64-bit everywhere, and the
`addresses'

Mine is also much better now - DRMKMS kernel boots into multiuser,
switches the mode and works fine in multiuser. Xorg doesn't start; it
blanks the screen and I presume panics, but I can't see anything; I
will have to switch to serial console to see what is going on (I also

I'm seeing basically the same thing with an RV280 on i386, I don't
have a crash dump as it goes into a recursive panic but was able to
capture a boot trace with a serial console.

I just tried a DRMKMS kernel on my laptop, (source updated less than an
hour ago) and compared to several months ago when I tried it last, it
gets a lot further!
I just tried the kernel though, no updated userland (so I have the old X
from 6.1).
I didn't really expect that situation to work, but
Adding some printfs to the kernel it doesn't look to be calling into
the drm code from the mmap() syscall.
Probably needs to be changed to use drmMap instead of mmap,
un{til,less} we sort out getting proper mmap for non-vnode files.
i commited the fix for this i've been using.
