It may, or may not, be the fault of linuxbios:
Things to check for hints:
    dmesg
    /var/log/sys

Usually the root file system is first mounted ro and the startup routine
checks the file system. If ok, root is then remounted rw. Slackware does
this in rc.S.

Did you edit any rc files? if so, you may have forgotten to chmod +x.
