Hi all,
I just ran into a regression with booting RISC-V kernels due to this
commit. I can reproduce it with QEMU 5.1.0 and latest tip of tree
(25f6dc28a3a8dd231c2c092a0e65bd796353c769 at the time of writing this.)
I have attached the rootfs and kernel image used for these tests. If for
some reason there is a problem receiving them, the kernel is just an
arch/riscv/configs/defconfig kernel at Linux 5.9-rc2 and the rootfs is
available here:
https://github.com/ClangBuiltLinux/boot-utils/blob/3b21a5b71451742866349ba4f18638c5a754e660/images/riscv/rootfs.cpio.zst
Please let me know if I can provide any follow up information or if I am
doing something wrong.
