Hello, My OS is Ubuntu 22 and I am using gem5 v22.0.0.1, when I boot a Ubuntu 22 image I got error: *Kernel panic - not syncing: Attempted to kill init! exitcode=0x00007f00* Attached are the logs, could anyone help to find the problem? Thanks in advance. Best regards, Zhenwen Hu

Hi Zhenwen, The actual error is one line higher in the kernel output: `/lib/x86_64-linux-gnu/libc.so.6: CPU ISA level is lower than required` I believe we fixed the incompatibility of gem5-x86 with newer kernels in gem5-v22.1, but it is definitely fixed in gem5-v23.0. I suggest either updating gem5 or downgrading your kernel and Ubuntu image to something older. See https://gem5-review.googlesource.com/c/public/gem5/+/64831 and https://gem5-review.googlesource.com/c/public/gem5/+/65492 Cheers, Jason On Thu, Jul 27, 2023 at 9:40 PM Zhewen Hu via gem5-users < gem5-users@gem5.org> wrote: > Hello, > > My OS is Ubuntu 22 and I am using gem5 v22.0.0.1, when I boot a Ubuntu 22 > image I got error: > *Kernel panic - not syncing: Attempted to kill init! exitcode=0x00007f00* > > Attached are the logs, could anyone help to find the problem? > > Thanks in advance. > > Best regards, > Zhenwen Hu > _______________________________________________ > gem5-users mailing list -- gem5-users@gem5.org > To unsubscribe send an email to gem5-users-leave@gem5.org >

Hi Zhenwen, If you're trying to boot an x86 or risc-v image, you can find scripts for it in gem5-resources: https://gem5.googlesource.com/public/gem5-resources/+/refs/tags/v22.1.0.0/src/(x86-ubuntu, riscv-ubuntu). I was also facing similar issues and this helped me.

Hi all, As mentioned above, the problem is likely due to using KVM then switch to another gem5 core, which doesn't support all ISA extensions that the host supports. I wanted to add that, if updating the gem5 version doesn't solve the problem, you can use AtomicSimpleCPU for fast-forwarding instead of KVM.
