https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=261749 Bug ID: 261749 Summary: radeonkms corrupts kernel (panic) when being unloaded Product: Base System Version: Unspecified Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: email@example.com How to reproduce: 1. kldload radeonkms (no matter whether via rc.conf or manually via console. It loads even if there is no radeon hardware present!). 2. kldunload radeonkms. 3. kldload nvidia. BANG! GPF PANIC! It happens no matter whether sc or vt console are being used. This issue is particularly annoying when you swapped the radeon graphics card for a nvidia one and want reconfigure the system to run with the nvidia, after booting with the rc.conf still containing the radeonkms module kldload. Because, it should not be necessary to have to reboot only because of radeonkms corrupting the kernel. Test system is HP Z800 with FreeBSD 13-RELEASE-p7. Nvidia driver here is 390 (Quadro 2000). But my feeling is the Nvidia driver version will not matter. -- You are receiving this mail because: You are the assignee for the bug.
