This is from the ancient mkfs.c (which actually violates the BSD style
guide...  exit points should not be `numbered').

/*
 * write a block to the file system
 */
wtfs(bno, size, bf)
        daddr_t bno;
        int size;
        char *bf;
{
...
        n = write(fso, bf, size);
        if (n != size) {
                printf("write error: %ld\n", bno);
                perror("wtfs");
                exit(36);
        }
}

So it looks the `write' system call fails for some reason.  I guess
it's an unrecovered hardware write error.  Maybe the second screen
(Alt-F2) will tell you more.
