我6.1内核之前有很严重的断流问题（大概不到十分钟就断一次），后来进内核开了rtw89驱动之后有很大改善，不过偶尔还是会断

貌似是arch带的编译器版本太高了
用老编译器编的内核可以正常使用panthor

@plumlis I tried. Seems that the file from linux-firmware package in archlinux arm is the same as file from this site.

Hello, I' m trying to use archlinux arm on pi cm5 laptop v20. The kernel I use is from github repo of cool-pi offcial, both 5.10 and 6.1 have been tried. In addition, I need to regenerate initrd.img by myself using dracut. I simply copied uboot from ubuntu img.
Both kernel can boot into system, but issues exist:
When booting from 5.10, I need to build mesa with panfork support from aur, and then I can use hardware acceleration in X11. However, entering plasma wayland will cause a black screen, and I can't input anything except poweroff.
If using 6.1, version of mesa from archlinux arm is 24.1.4 and linux-firmware package contains gpu firmware, which is at /lib/firmware/arm/mali/arch10.8/mali_csffw.bin. However I can't use any of hardware acceleration. Here is the dmesg:

It's certain that file /lib/firmware/arm/mali/arch10.8/mali_csffw.bin exists. I have to use llvmpipe.
And sound system seems not working on kernel 6.1.
