安装驱动后也无法驱动，后发现启动后重新加载驱动能正常驱动，故通过添加启动服务的方式重加载驱动解决问题，有相同问题的人可以参考
问题
使用 dmesg | grep -i i915命令确认
root@fnos:~# dmesg | grep -i i915
[ 1.532247] i915 0000:06:10.0: [drm] Found ALDERLAKE_S/RPL-S (device ID a788) display version 12.00 stepping D0
[ 3.533673] i915 0000:06:10.0: [drm] *ERROR* Device is non-operational; MMIO access returns 0xFFFFFFFF!

[ 3.534720] i915 0000:06:10.0: probe with driver i915 failed with error -5
可见，驱动加载失败了，现在使用 modprobe -r i915 && modprobe i915重拉驱动
root@fnos:~# modprobe -r i915 && modprobe i915
root@fnos:~# dmesg | grep -i i915

可见重拉后驱动加载成功了，下面为了让它每次重启自动重拉驱动我们需要创建一个服务
创建服务文件
sudo vim /etc/systemd/system/delayed-reload-i915.service
编辑内容：
[Unit]
Description=Delayed reload of i915 driver for SR-IOV
[Service]
Type=oneshot
ExecStart=/usr/sbin/modprobe -r i915
ExecStartPost=/bin/sleep 2
ExecStartPost=/usr/sbin/modprobe i915
TimeoutSec=60
RemainAfterExit=yes
启用并启动服务
sudo systemctl daemon-reload
sudo systemctl enable --now delayed-reload-i915.service
