 Grmpf.
 
 First, please limit your linelength to a reasonable value.
 
 Second, you should be as exact as possible.  ``Cannot mount root'' is
 the panic.
 
 Third, you should read docs, and failing this, please ask this to the
 proper support forums (questions@freebsd.org, or in Usenet).  There
 are a lot of people being able to answer this, and no, it's not a bug.
 Thus, it's neither critical nor deserves a high priority.
 
 (Fourth, you could do a minimal effort of examining the problem
 yourself.  Your bootmessages would show you that the disk where the
 root filesystem was expected to be on simply hasn't been found.)
 
 Finally: "0:wd(2,a)/kernel" is the boot string.  ``man nextboot'' to
 see how to make the change permanent.
