https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=285588 Bug ID: 285588 Summary: Bootloader panics with AMD Radeon Pro W5500 GPU with free: guard2 fail message Product: Base System Version: 14.2-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: dguthrie@posteo.net I have an AMD Radeon Pro W5500 GPU, which installed in a Lenovo Thinkstation P5 workstation. This boots fine with Linux (and I get to X11/Wayland there). 15.0-CURRENT boots to the point of loading the installation programme, but it doesn't seem to work on earlier versions. In fact, it immediately crashes when I try booting the following: 1. An installation of 14.2-RELEASE which I made after replacing the GPU with another, on this workstation. 2. A 14.2-RELEASE installer image 3. A 14.2-STABLE snapshot with timestamp 20250306-057409d0259f-270695 4. An installation of 14.2-RELEASE from my Thinkpad X201s laptop (with Coreboot+EDK2 EFI) Booting the installation (#1 above), after installing the Radeon Pro W5500 GPU, I get the following behaviour. This is at the earliest stages of the bootloader proper, not anything to do with radeondrm or amdgpu drivers from ports. The message is: panic: free: guard2 fail @ 0x51e302d0 + 155521 from unknown:0 --> Press a key on the console to reboot <-- The FreeBSD logo is displayed, and keyboard input does work. If I press a key, it does reboot. The following text precedes the message. It is transcribed from a video because the crash happens almost immediately, so there may be transcription errors. I have omitted the UUIDs.

It's so quick, it's not captured on a frame), then the final guard2 fail message. -- You are receiving this mail because: You are the assignee for the bug.home | help
