Got a 9060 xt yesterday and after some troubleshooting including putting it into my desktop I confirmed that the issue is a truenas driver problem and not a problem with card itself.
Specifically on boot:
amdgpu 0000:0d:00.0: Direct firmware load for amdgpu/psp_14_0_2.sosbin failed with error -2
[drm:amdgpu_device_init [amdgpu]] ERROR early_init of IP block failed with -19
And a few other similar errors. One for vcn_v5_0_0, one for gfx_v12_0, one for gc_12_0_0_uni_mes.bin, one for dcn_4_0_1_dmcub.bin
which repeats a few times until:
[drm:sdma_v7_0_early_init [amdgpu}} ERROR Failed to init sdma firmware!
and then a final “fatal error during GPU init”
I don’t recall seeing the devs state if they would move to Trixie in the 25.10 release, or what kernel version will be used. It’s quite possible I missed it though.
Generally, getting bleeding edge hardware is going to be a painful experience in an appliance OS that priorities stability over the ability to use the newest hardware.
