Kernel panic on poweroff #122

Closed dilyanpalauzov closed 3 years ago

dilyanpalauzov commented 3 years ago

With Qemu 5.2 I start

qemu-system-arm -dtb ./versatile-pb-buster.dtb -kernel ./kernel-qemu-4.19.50-buster -cpu arm1176 -m 256 -M versatilepb -append "root=/dev/sda2 rootfstype=ext4 rw" -drive driver=raw,file=./2021-01-11-raspios-buster-armhf.img,index=0,media=disk -serial stdio

then I log in and type “sudo poweroff”. The system prints:

[ OK ] Stopped Create System Users. [ OK ] Stopped Remount Root and Kernel File Systems. [ OK ] Reached target Shutdown. [ OK ] Reached target Final Step. [ OK ] Started Power-Off. [ OK ] Reached target Power-Off. reboot: System halted Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000000

Can you provide hints how to achive clean termination, rather than kernel panic?

This has been fixed in QEMU v6.1.0-rc0.
