I installed a new stable version FreeBSD 12.1-STABLE r364184 GENERIC amd64.
Twice in mode mountroot.
put on /dev/**9s*
and the device really became /dev/**0s*
rebooted history repeated itself.
Then he deleted everything. and put it back.
mountroot means that the kernel cannot determine which disk to use for the root, usually a result of a configuration problem. If you do not provide any input at the prompt, the kernel will panic, it is expected. Are you claiming that the panic is a bug?
The problem is that I can’t do anything. Pakina comes immediately. And you have to put it first.
panic in mountroot mode.((((((((((((((((
