https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D237544 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: bugs@FreeBSD.org Reporter: sigsys@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 kmo= d).=20 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-REL= EASE 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 its= elf after starting Xorg (then switching back to a console VT has a black background).
