这几天在惠普战66三代amd笔记本上尝试安装deepin v23，发现安装引导界面和安装后重启界面总是有高概率黑屏有背光，此时无法操作了，只能重启再来....（下图是黑屏前必然出现的日志）

好不容易凑巧有一次一路正常安装进桌面，此时会在上图的基础上打印日志：

amdgpu: Secure display: Generic Failure.
amdgpu: SECUREDISPLAY: query secure display TA failed. ret 0x0

看了一下有xorg的coredump：

xorg日志（我后来重装了mint，现象是一样的，这里拿mint上的xorg代替一下）：

但是从这个日志上看，显然出现了bios_parser2.c中的指针越界。内核6版本amdgpu的drm驱动源码中是这么写的：

看起来算错是因为 le16_to_cpu 这个宏计算错误，但是这个宏貌似是上游linux内核中的，不太可能有问题。

暂时没找到办法，尝试直接添加内核参数 amdgpu.dc=0 来跳过这个 dc 模块，尝试了不行... 所以目前只能用 nomodeset 禁用显卡驱动来勉强使用，但是这么不是办法，毕竟 nomodeset 下缩放和锯齿有严重问题。

这个黑屏的现象，我在deepin\ubuntu\mint上都发现了，各位大佬有什么办法吗？
