compiled kernel can NOT boot without trying to mount root

[lvii]

Hi

I have rebuilt kernel to enable Netflix RACK TCP stack on FreeBSD 12.0 new created vultr VPS by following this blog:

https://calomel.org/freebsd_network_tuning.html

# cat /usr/src/sys/amd64/conf/CALOMEL
include GENERIC
ident   CALOMEL
makeoptions WITH_EXTRA_TCP_STACKS=1
options TCPHPTS

Boot failed after reboot with new kernel, hang without trying to mount root :

old kernel booting would try mount / root :

One thing I've learned over the past 15 or so years of using FreeBSD, don't tune for the sake of tuning. Only tune when there's an actual need for it.
