我用了 Deepin 25.2.0 试试：
dd if=deepin-desktop-community-25.2.0-loong64.iso of=/dev/sdb status=progress
开启电脑的时候选 U盘，然后：
1.选 Try Deepin Desktop 25 给我：
[ 0.000000] lpc: Failed to get LPC status
2.选 Install Deepin 25 with kernel 6.18 desktop 给我：
lpc: Failed to get LPC status

3.选 Install Deepin 25 with kernel 6.6 desktop 给我：

上面的信息都是用 USB2.0 接口。
用 USB3.0 接口的话，rcu 的信息都没有了：
1.选 Try Deepin Desktop 25 给我：
lpc: Failed to get LPC status
2.选 Install Deepin 25 with kernel 6.18 desktop 给我：
lpc: Failed to get LPC status
3.选 Install Deepin 25 with kernel 6.6 desktop 给我：
lpc: Failed to get LPC status

现在要试试 openkylin。
