This happens if the machine was improperly shut down with files open
(eg someone cut the power) and if the system is getting disk read/write
errors - which indicates the disk may be failing.
You got booted in to single user mode when the automatic fsck failed.
Nothing but a special semi-mount of / is available.
The first is generally easy to recover from.
Just do a manual fsck
When it asks that Enter Full pathname question, just hit RETURN/ENTER
type fsck -p (or fsck -f if you have patience and can wait)
Answer yes to any prompts - you don't have much choice anyway unless
you want to get really sophisticated about recovering lost stuff -
mostly it will just be orphan blocks of disk that need relinking.
When it finishes, reboot the system with 'shutdown -r now' or try
doing a CTRL-D to end single user and complete the original boot, but
I am skeptical [paranoid] and just do the whole reboot under those
sorts of circumstances.
If it is because of a failing disk, try the same thing and then
immediately make a backup of as much as you can and start ordering
a replacement disk. If the disk is beginning to fail, you may get
it back to working for a short while, but it is ultimately doomed
so back up very often and get a new one in as soon as you can.

Probably it was not mounted - is either your /usr or /usr/src directory
in its own mounted file system or is /usr/src living somewhere else
with a link? If so it is not mounted when you are first in single
user mode. If the above fsck works and finishes, then you can do
mount -u /
mount -a
swapon -a
and then you should be able to get to /usr/src, etc. You can poke around
and check things out. But probably just the reboot is all you really want.
