I just checked again and I can confirm it is this patch that causes the regression. This is the command line: qemu-system-riscv64 \ -machine virt -m 64M \ -cpu rv64,mmu=false \ -serial mon:stdio -serial null -nographic \ -append "root=/dev/vda rw highres=off console=ttyS0 mem=1G ip=dhcp earlycon=sbi" \ -device virtio-net-device,netdev=net0,mac=52:54:00:12:34:02 -netdev user,id=net0 \ -object rng-random,filename=/dev/urandom,id=rng0 -device virtio-rng-device,rng=rng0 \ -smp 1 -d guest_errors \ -kernel ./images/qemuriscv64/nommu-Image \ -drive id=disk0,file=./images/qemuriscv64/nommu-rootfs.ext2,if=none,format=raw \ -device virtio-blk-device,drive=disk0 -bios none You can access the images from: https://nextcloud.alistair23.me/index.php/s/a2zrtbT7DjdTx9t Alistair > > Thanks, > Jason
