Quite possibly because the damn thing claims it's "V", but in fact
it's not compatible with the V1.0 spec. Sadly it's a common problem
for these V0.7.1 systems.
I've seen kernel patches floating around that mask the __riscv_hwprobe
flags for those machines. Haven't they been merged?
Dunno. I know there's patches out there, but no clue if they're been
merged and if there's all the bits needed to build a new kernel that'll
work on that system.
Ours has been so flaky that we don't use it much.
