T= he machine in question is a Lenovo Thinkpad P16s G2 (AMD; Type 21K9) running a recent version of FreeBSD 15: FreeBSD perugia 15.0-CURRENT FreeBSD 15.0-CURRENT #0 main-n269029-a983cea4e= 9a8: Thu Mar 28 17:26:19 CET 2024=20=20=20=20 root@perugia:/usr/obj/usr/src/amd64.amd64/sys/GENERIC amd64 dmesg reports about the CPU as follows: ----8<---- CPU: AMD Ryzen 7 PRO 7840U w/ Radeon 780M Graphics (3293.91-MHz K8-class = CPU) Origin=3D"AuthenticAMD" Id=3D0xa70f41 Family=3D0x19 Model=3D0x74 Step= ping=3D1 ---->8---- pciconf -lv reports about the graphics controller: ----8<---- vgapci0@pci0:100:0:0: class=3D0x030000 rev=3D0xdd hdr=3D0x00 vendor=3D0x1= 002 device=3D0x15bf subvendor=3D0x17aa subdevice=3D0x50da vendor =3D 'Advanced Micro Devices, Inc.

Loading amdgpu.ko from graphics/drm-61-kmod causes a kernel panic (see attachments). Prior to installing FreeBSD, this machine ran fine -- graphics included -- = with Lubuntu 22.04.3. This might be related to Bug 268394; the interim solution presented there unfortunately doesn't work in this case as we can't fit a dedicated graphics card. --=20 You are receiving this mail because: You are the assignee for the bug.=
