building a kernel on a 9p/virtio mount (tried tmpfs underneath first,
but also fails with xfs on a "slow" disk)
reproduced this as well, should be easier to play with than getting
RDMA.
It's actually failing alot faster, so will try to get simpler
reproducers with that again.
no specific mount option.
