graphics/drm-61-kmod amdgpu panic: Unregistered use of FPU in kernel #277
Comments
Test this patch:

I tried the patch, but unfortunately it does not make any difference. panic: Unregistered use of FPU in kernel |
Ok. Then let`s increase DC_FP scope:
|
That made a difference! |
Same problem on : Patch works here too. |
Patch works also for: Thanks! |
(Maybe a different problem? But,) I also have a panic using drm-61-kmod on FreeBSD 15.0 It's an APU (raphael) on aAMD Ryzen 9 7900X b.f.o issue for reference: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=268394#c10 |
Sorry, unfortunately I can't "read" the image. Is the problem: "panic: Unregistered use of FPU"? |

I pushed slightly different version of the patch to 6.1-lts branch. If it still works we can update drm-61-kmod port |
That is different panic. What you see is a driver unloading bug (misplaced vm_phys_fictitious_unreg_range() call). It is triggered by a fatal error (not by the driver crash!) during initialization. You should check message buffer content rather than backtrace in that case. Most probably the reason of error is unsupported GPU or missing firmware module. |

Thanks, and sorry for my late answer. Different problem now with 61-lts, I can load amdgpu, but now, I have black screen. I was unable to compile the 6.6 branch due to a missing header: |
Closing as the original bug is fixed. |
