I am trying to run the Linux kernel version 5.15.71 available here https://github.com/projectacrn/acrn-kernel/tree/release_3.2 as a Service VM under ACRN hypervisor. I am mainly following their "Getting started" guide available here https://projectacrn.github.io/latest/try.html.
I have managed to run the hypervisor (I can see from the logs) but the Service VM is not starting. For some reason the Service VM kernel is panicking with the following message.
Kernel panic - not syncing: Fatal exception in interrupt[ 26.083409] Kernel Offset: 0x13000000 from 0xffffffff81000000 (relocation range: 0xffffffff80000000-0xffffffffbfffffff)
I have extensively searched on the internet and have tried several options but none seems to work. I know this might not be the right place to ask this question but since the issue is related to Linux kernel and ACRN itself does not have a large community, I am putting it here (already posted a question there few days ago and still waiting for a response).
Partial kernel log of the Service VM is given below with lines before the panic. My main question is what can be the potential reasons for kernel to panic and what should I try as a solution. Just for clarification, the hardware seems to be fine because I have several other kernels booting normally on the same hardware.
Thank you
