HP/Compaq nc8430 laptop with ATI Mobility 1600X (R520) GPU was stable in 13.2 with radeonkms module loaded. Panics at boot when the module is loaded since upgraded to 13.3-RELEASE Tried deinstalling/reinstalling drm-510-kmod-5.10.163_9 gpu-firmware-kmod-20240401,1 drm-kmod-20220907_3 to no avail.

I don't understand, in #270563 you said that it hang with 13.X but worked with 12.4 and now you say that 13.2 worked here ? Anyway, don't expect much help for this issue because : 1/ It's i386, no body cares about it 2/ It's radeonkms, no body cares about it Cheers,
(In reply to Emmanuel Vadot from comment #2) Thanks for your reply but you haven't read bug #270563 completely if you're asking. - 12.4: no issue at all - 13.2: X hangs if the R520 firmware is present and loaded, works OK otherwise (presumably without acceleration - I don't care) - 13.3 : panics when radeonkms loads, unusable As for the rest of your comment, well, that's quite helpful, thanks. Guess I'll be back to Linux then, I wanted to give FreeBSD a chance on this old laptop in memory of the years I used FreeBSD extensively at an ISP I was working for. The latest Debian 12 works flawlessly on this old notebook. I still like FreeBSD more, but apparently it's hopeless then.
Created attachment 250955 [details] patch-drivers_gpu_drm_radeon_radeon__device.c If you're still interested you could try this patch. It's an attempt to address the radeon_atombios_init error. Put the file in /usr/ports/graphics/drm-510-kmod/files/ and rebuild the port.
Thanks, I'll try it. FYI I just upgraded a HP Probook 6570B Core i5 machine (hence running FreeBSD/amd64 to 13.3-RELEASE and I have the same crash. Don't know if I'm supposed to open another bug or if it's no use.
Still causes panic on my HP Probook 6570B when I load the module. I'll open a different bug because I'm not sure it's the same exact issue here. Since it's amd64, maybe I can hope for more attention.
Sorry for spamming. Standby. I've just somehow managed to build a module that works on the PB 6570B (amd64 machine). Very confused. This is without the patch, after updating my ports tree from "latest". I will try to make sense out of this, try again on the older i386 machine and come back to comment.
