Bug ID: 237544
Summary: panic on 12-STABLE with Radeon HD 7450 under
drm-fbsd12.0-kmod but not drm-fbsd11.2-kmod
Product: Base System
Version: 12.0-STABLE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: b...@freebsd.org
Reporter: sig...@gmail.com
I have a computer with a Radeon HD 7450 that panics when using the
drm-fbsd12.0-kmod driver but works OK with the drm-fbsd11.2-kmod one. It
usually takes a few days to panic (after which I revert it to the older kmod).
Can't tell if it's doing something in particular that triggers it (but that's
with browsers and media players always opened). It did this under 12.0-RELEASE
as well. I tried the newer kmod after upgrading to 12-STABLE to see if that
fixed it, but it still panics.
That's with radeonkms. amdgpu doesn't work with it (loading it does not
recognize any video card it seems). I did not have the xf86-video-ati or
xf86-video-amdgpu Xorg drivers installed. I take it they are not needed
anymore?
Also oddly enough the screen has a bright gray background after the module
loads. The text is still readable but very difficult to read. It fixes itself
after starting Xorg (then switching back to a console VT has a black
background).

I'll try again next time the driver gets updated.
