Let me take a look: what's your config and the base commit? Please try the alexghiti_test branch at: https://github.com/avpatel/linux.git Compile the kernel with defconfig and launch QEMU as follows: qemu-system-riscv64 -M virt -m 1G -nographic -bios opensbi/build/platform/generic/firmware/fw_jump.bin -kernel ./build-riscv64/arch/riscv/boot/Image -append "root=/dev/ram rw console=ttyS0 earlycon" -initrd ./rootfs_riscv64.img In the above command, rootfs_riscv64.img is a busybox based rootfs.
