Description Tomasz "CeDeROM" CEDRO 2024-09-07 21:20:29 UTC

kldunload amdgpu causes kernel panic / screen crash:
* for drm kmod 5.10 it leaves computer without screen but responsive there is still a ping reply, i can work over ssh, i can reboot with ctrl+alt+del.
* for drm kmod 5.15 and 6.1 there is a kernel panic (not visible on screen as there is no screen anymore).
* default vt / efifb console should be restored on module unload so the machine is still operational over screen and keyboard.

current module versions: drm-510-kmod-5.10.163, drm-515-kmod-5.15.160, drm-61-kmod-6.1.92.

FreeBSD 14.1-RELEASE-p4 AMD64.
