>From the OE side we simply don't have people able to dig into this kind of problem in detail unfortunately. I'm also travelling at the moment which just complicates my own availability. I am pleased you can replicate it and have been able to dig into it a bit. My own theory was something like the timer interrupts stalling since I've seen that problem on two other occasions recently on x86 and ppc due to totally different issues but it sounds like you've ruled that out. At least from a replication standpoint it happens with a second of the kernel boot so you don't need the rootfs and can likely script a fast "brute force" of the issue (restart qemu until it hangs in boot). I can confirm we continue to see the problem on our builds and it is causing a real problem for us as we can't tell whether qemuarm64 is really failing or just hanging :( Any help in getting this figured out is much appreciated!
