Hello, I use qemu 5.2. This expect script:
#!/usr/bin/expect -f set timeout -1 spawn 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 -nographic expect "login: " send "pi\n" expect "Password: " send "raspberry\n" expect "$ " send "sudo poweroff\n" expect "panic" exec kill -9 [exp_pid] close send_user "THE END\n" --- called with `time` ends with the text ---- [ 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 syncTHE END real 2m16.174s user 0m0.092s sys 0m5.359s ------ but the same script without the panic line, when called with `time` ends with: raspberrypi login: pi Password: Last login: Wed Jan 27 21:16:53 GMT 2021 on tty1 Linux raspberrypi 4.19.50+ #1 Tue Nov 26 01:49:16 CET 2019 armv6l The programs included with the Debian GNU/Linux system are free software; the exact distribution terms for each program are described in the individual files in /usr/share/doc/*/copyright.

In fact, the kill and close lines are not necessary, this script: #!/usr/bin/expect -f set timeout -1 exec cp E/2021-01-11-raspios-buster-armhf.img . spawn 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 -nographic #-D qemu_log -trace file=f expect "login: " send "pi\n" expect "Password: " send "raspberry\n" expect "$ " send "sudo poweroff\n" expect "panic" send_user "THE END\n" called with time, ends in: [ OK ] Stopped Create System Users.
