Dear gem5 community,
I have successfully simulated the HPCG benchmark using ARM Ubuntu in
gem5 in 2 cores. However, when I try to simulate it using more cores
(i.e. 8 cores) it takes more simulated time, and I get the following
kernel panic after approximately 20 hours of simulation:
[ 8.580827] Kernel panic - not syncing: Attempted to kill init!
exitcode=0x00000000

I use the following cmd: $GEM5/build/ARM/gem5.fast --listener-mode=on
-r -d $GEM5/node0 $GEM5/configs/example/arm/starter_fs.py
--kernel=vmlinux.arm64 --num-cores=8 --disk-image=ubuntu-18.04-arm64.img
and I use the Latest Linux Kernel Image / Bootloader and Latest Linux
Disk Images from here
(https://www.gem5.org/documentation/general_docs/fullsystem/guest_binaries).
I really appreciate any help!
Best regards,
Nikos
