Bug ID: 253461
Summary: [AMD/ATI] RV730 PRO [Radeon HD 4650] panic kernel
Product: Base System
Version: 12.2-RELEASE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: b...@freebsd.org
Reporter: freebsd.68...@nospam.spacesurfer.com
I am running X11 on FreeBSD 12.2-RELEASE-p2 with a Radeon 4650. I am using the
radeonkms kernel module from drm-fbsd12.0-kmod-4.16.g20201016_1 /
gpu-firmware-kmod-g20200920 with the xf86-video-ati-19.1.0_3,1 driver. The
machine has 2 monitors running at resolution 1920x1200.
With this setup the machine randomly panics (can be after days). This seems to
happen most often when the screen saver kicks in and the monitors are put to
sleep.
The last time I go a kernel dump which reports the following:
[694796]
