I'm trying to debug a KMSAN related issue. To do so I created a QEMU instance to replicate the bug, however, it gets stuck at startup. 

It gets stuck after saying:

Has anyone experienced something similar?

Do you have any idea of which configuration options I should look into?

To give some context: I'm working on an ARM64 machine, and I'm cross compiling the kernel for x86_64 using clang.

Thanks!
