[Bug 297250] graphics/drm-66-kmod (amdgpu): panic: Assertion td->td_lkpi_task == NULL

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D297250

--- Comment #1 from Klaus K=C3=BCchemann <[email protected]> ---

well, in the end I could workaround this bug  by trial&error in the followi=
ng
sequence :
1. =E2=80=94 solution (important to install BOTH drm&firmware via ports)=E2=
=80=94
pkg delete [everything drm-kmod & gpu-firmware-kmod]
pkg autoremove
cd /usr/ports/graphics/drm-kmod
make install
cd /usr/ports/graphics/gpu-firmware-kmod
make install

Maybe the above is a known sequence for some people who hit this issue but =
why
not fix this bug

2.=E2=80=94while worked around it  for now  I think I=E2=80=99ll leave this=
 bugzilla open since
the following related is for sure a kernel bug  :

This should be the (existing)correct way to prevent kernel crash/attack:=20
root@fbsd5pro:~ # kldunload  amdgpu_renoir_asd_bin.ko
kldunload: can't unload file: Device busy
=E2=80=A6with the addition of console-message :
kldunload: attempt to unload file that was loaded by the kernel

But :
 try to:
 kldunload amdgpu,
 ouch, massive crash(system tries to goto init1 and even fails that attempt=
 &
freezes)

3.=E2=80=94
Also I would suggest to =E2=80=9E forbid=E2=80=9C to install drm-kmod & gpu=
-firmware-kmod via
pkg=20
since version incompatibilities or whatever crap will massively pollute the
system and will crash X11 or kernel panic  .
Instead an attempt of using pkg should ONLY spit out a warning message AND
instructions to do it correctly via ports.
I know there is a message AFTER(why not before?) installation like :
If not good for your OS- version then rebuild ( w/o details howto remove the
crap and rebuild)
of course: fix instead of warn is even better :-)


O.K., above only as a conceptual approach , for me it=E2=80=99s fixed thank=
s to some
hints from the mailing list, thx :-)
.. if someone wants to close this report, O.K. for me

Thx @Mark Linimon for redirecting this to X11@ , Regards
