I have tried with the grub kernel cmdline mentioned, but the freeze is<br>
still happening at 'modprobe amdgpu'<br>
<br>
Is there an explicit list of kernel module dependencies that I could<br>
check in our kernel defconfig?<br>
<br>
I have also added Qiang, in case he may have ever seen the issue in<br>
his former Android experience<br>
