Hi all.
I just upgrade FreeBSD 13.2 to 14.0-RC3, and I try to driver my i5-1240P's alderlake GPU,
when I first run as root
Code: 
#kldload i915kms
It run normal in kldstat:

then run
Code: 
#kldunload i915kms
#kldload i915kms
and the system is halt!
Does anybody can help, please!

Afaik the drm kernel modules like i915kms do not support being unloaded.

thanks a lot!
But, by comment "kld_list="i915kms" line in /etc/rc.conf, that is, without autoload,
I reboot the system, just manual as root:
```sh
#kldload i915kms
```
but the system halt also.

Some are OK, some not. I can't find a reference, but I vaguely recall some improvements.

hopper886 this might be of interest, although I can't say that it's a match:

github.com

Race between drm and i915kms on unload when compat.linuxkpi.i915_enable_guc=1 · Issue #3 · freebsd/drm-kmod

After unloading i915kms and trying to kldload i915kms again the GuC firmware verification fails : drmn0: successfully loaded firmware image with name: i915/skl_guc_ver9_33.bin [drm ERROR :guc_wait_...
github.com github.com

Side note: many of the links in issue 3 are irrelevant. <https://codeberg.org/grahamperrin/freebsd-doc/issues/42> suggests an improvement to FreeBSD documentation, to help avoid the unwanted noise.

My <https://github.com/freebsd/drm-kmod/issues/168#issue-1242141237> includes a quote from 2022. In part: "… Subsequent unload of radeonkms succeeds, subsequent load of i915kms causes a panic …"
 
thx!

But when I reboot , not autoload, just manual run `kldload i915kms` as root, It halt also.

BTW: I try two method:
1. pkg remove gpu-firmware-intel-kmod-alderlake, reboot system , manual kldload i915kms, the system loaded without halt, but show message by dmesg that need load gpu-firmware, and gpu seems not work probably。
2. pkg install gpu-firmware-intel-kmod-alderlake, reboot system, manual kldload i915kms, then system halt!

In method 1 the system is loading the built-in i915kms module which is not compatible with your GC.
Try build the driver from ports.

There's no built-in module.

For quarterly graphics/drm-510-kmod, the most recent success was built for version 1400097 of FreeBSD. Does release candidate 3 have a different version number?

thx ur reply!

FreeBSD 14.0-RC3 ports include drm-510-kmod (drm-510-kmod-5.10.163_7) and drm-515-kmod (drm-515-kmod-5.15.118_1)
and I try install krm-510-kmod, and kldload i915, the system run and not halt, but the gpu can't work properly
( whenever install port gpu-firmware-intel-kmod-alderlake-20230210_1 or not )
