Crash on loading i915kms, fresh 14.1 install

[shivars]

Hi,

I have a clean 14.1-RELEASE install, which installs and works fine - but I get a hard crash as soon as I try to load i915kms.

The hardware is a 13900K on a Z690 chipset, with Intel UHD 770 onboard graphics plus 2 x Intel ARC A380 graphics cards - so I guess not too exotic in terms of chips, but probably unusual in the configuration :/ Its a fresh install of latest 14.1-RELEASE, with nothing else on it. The crash happens every time, after cleanly booting up and just running `kldload i915kms`. This is with the latest drm-61-kmod package installed.

I couldn't see how to get any more useful info yet than the screenshot below - /var/crash doesn't have much, and I can't seem to get a dump of the messages shown in the screenshot (they're not present in dmesg after rebooting).

Any help appreciated - and/or any pointers as to where I can find more useful diagnostics info. If the next step is to start re-plugging hardware then so be it, although hopefully not

Hardware probe outputs here (albeit the sites look down at the moment): https://linux-hardware.org/?probe=b0168ae6f4 / https://bsd-hardware.info/?probe=b0168ae6f4
(NB I had a similar/same-looking crash on the same hardware under 15.0-CURRENT, which I wrongly posted in a reply here - just in case that's relevant)

Thanks

Look at the screenshot: you don't have the firmware installed.

Even if the firmware is not installed, the system should still not crash. shivars should file a bug.

Thanks.
Tbh I should have noted that I'd seen that message, and installed the requisite package, and still had the same message and crash. That said, my memory is a little hazy right now on whether that was on the current 14.1-RELEASE install, or the previous attempts on 15.0-CURRENT. I'll give it another try and report back.
