Solved CURRENT halts on kldload amdgpu.ko

[sify]

hi,
I'm using a Lenovo t495 laptop which according to

Laptops - FreeBSD Wiki

should work out of the box.
However when I freshly install the OS, and try to

pkg install drm-kmod
kldload /boot/modules/amdgpu.ko

the system freezes.
the drm is a 20220501 version

setting

• hw.syscons.disable=1

stops the system on boot even before loading kernel modules (I am using uefi boot)

probe:

HW probe of Lenovo ThinkPad T495 20NJ00... #078888676a

A database of all the hardware that works under bsd

bsd-hardware.info

I was so happy finally seeing support for my HW and got kinda confused why it crashes

-CURRENT is an unsupported, developement version.

i've just installed RELEASE and i'm getting the same issue.
i'm following the manual:

Graphics - FreeBSD Wiki

after reboot, the system stops at
Loading kernel modules:

 

[SirDice]

System doesn't stop. hw.syscons.disable=1 disables the video framebuffer, so you don't see anything. Setting shouldn't be needed anymore though. Just remove it.

i've just installed RELEASE

Which supported RELEASE have you installed: 12.3, 13.0, 13.1 ?

pkg install drm-kmod

Try on 13.1-RELEASE graphics/drm-510-kmod. It needs to be build from ports, no package available on 13.1. Make sure to have the FreeBSD source installed when building the port.

From https://bsd-hardware.info/?probe=078888676a:

installing from port on RELEASE helped!
also /laptops could get an update, because t495 wifi worked out of the box on RELEASE too
very, very happy :3

ty all!
