Public bug reported:
I tried to do a routine upgrade and reflash of the Launchpad riscv64
builders, which pulled in linux-image-5.11.0-1017-generic
5.11.0-1017.18~20.04.1. The resulting image failed to boot with the
following (complete) console output:
Device 0: QEMU VirtIO Block Device
Type: Hard Disk
Capacity: 71680.0 MB = 70.0 GB (146800640 x 512)
... is now current device

### ERROR ### Please RESET the board ###
For the time being I've set `U_BOOT_DEFAULT="l1"` in
`/etc/default/u-boot` to force it back to the 5.8 kernel, although
that's obviously not very robust. Let me know if there's anything else
useful I can provide. The full image is kind of massive (70G, though
sparse so with only 13G of actual data), so I hope you can reproduce it
with something more stripped-down.
I've attached the libvirt domain definition.
