https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D278212 Bug ID: 278212 Summary: amdgpu / AMD Radeon XT 6900 - kernel panic (page fault) on FreeBSD 14.0-RELEASE-p6 Product: Base System Version: 14.0-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: jon@xyinn.org Created attachment 249782 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D249782&action= =3Dedit core dump Hello all, I few weeks ago I started experiencing a kernel panic with my AMD Radeon XT 6900 XT (although I don't necessarily think it's a regression, but maybe something related to my workflow with my KVM). I'm on FreeBSD 14.0-RELEASE-= p6, and was compiled the sources in order for me to eventually successfully cap= ture a kernel dump (attached). root@leslie:/usr/src # uname -a FreeBSD leslie 14.0-RELEASE-p6 FreeBSD 14.0-RELEASE-p6 #0 releng/14.0-n265417-d338712beb16: Tue Apr 2 19:26:31 EDT 2024=20=20=20=20 root@leslie:/usr/obj/usr/src/amd64.amd64/sys/GENERIC amd64 drm-kmod-20220907_1 gpu-firmware-amd-kmod-sienna-cichlid-20230625 I usually notice this happening when I start up my FreeBSD desktop while the KVM is currently active on my other laptop. I let FreeBSD (cold start since resuming from sleep doesn't work on this desktop) start up in the background and continue using my laptop in the meantime. Once ready, I hit the KVM but= ton, and everything starts to switch over to the desktop, after a few seconds of waiting, instead of me seeing the FreeBSD login prompt, I sometimes see the initial system start up screen, or some other early stage FreeBSD process. Essentially the system had a kernel panic and restarted. Once I wait for the system to start up again, I can see that it mentions a page fault, and the system works normally. I do believe this may have happened to me while I was using the system normally, but it seems to have a higher probability of happening with that KVM switch workflow. Please let me know if there is anything else I can provide. Thank you! --=20 You are receiving this mail because: You are the assignee for the bug.=
