Hello together,

i use the branch JH7110_VisionFive2_devel to build a custom kernel with starfive_visionfive2_defconfig.

Without add or delete any config option i see a kernel crash

Hi, Did you manage to make it work? If not, I can help. My kernel builds from there from this branch are fine. But I don't use VF2 to full right now, just ssh-ing to it. Also, try blacklisting jpu and vdec first. From backtrace it's evident that they cause some malfunction.
