编译内核后reboot
到最后就出现下面的错误： 不知道是为什么？

Mounting root from ufs:/dev/ad0s3a
setrootbyname faild
ffs_mountroot: can't find rootvp
Root mount failed: 6
Manual root filesystem specification
        <fstype>:<device> Mount <device> Using filesystem <fstype>
                eg. ufs:da0s1a
        ? List valid disk root devices
        <empty line> About manual input       


也不知道怎么加载文件系统

Freebird

内核配置文件呢？是不是把FFS也去掉了？

options          FFS               # Berkeley Fast Filesystem


我没有去掉

我没有去掉

请给出内核配置文件和/etc/fstab

我现在进不去freebsd
不知道还有怎么办法吗

Freebird

boot /boot/kernel.old
