AMD RX550 高频率出现 gpu reset 问题

[zhongtaifeng]

硬件：XA61200 + 3A6000
系统: gentoo
内核: 6.6.8 , 6.7.0-rc7 , 6.7.0

使用中， 反复出现 gpu reset

在使用 freerdp , qemu , 以及使用 webkit 的浏览器的过程中， 极高频率出现 gpu reset

但不限于这些应用， 甚至 gnome-text-edit 也会引发 gpu reset , 规律无法锁定

此问题在 loongarch 交流群有多人出现此问题， 现在还没能锁定是否单独这一款显卡出现此问题， 已再次尝试购买一张 RX6400 显卡进行下一步验证

It may be related to a hardware issue (hazard in HyperTransport) explained in chenhuacai/linux@a1e31fe. But it's just a "may" and the workaround is for radeon, no workaround has been developed for amdgpu yet.

目前 替换为一块 R5 240 使用 DisplayPort 输出口的显卡, 情况终于变的正常.

我也遇到了这样的问题。我是在跑SPEC CPU 2017，跑一段时间看看它，怎么动鼠标键盘，屏幕都不亮，没有显示输出。ssh进去一看，SPEC CPU 2017在正常跑，显示挂了。一看dmesg信息，gpu reset。
