    I confirm a got this one too.
    On a working kernel on an Opteron, we have normally 4 directories
    in /dev/oprofile :

    # ls -ld /dev/oprofile/?
    drwxr-xr-x 1 root root 0 15. Nov 12:38 /dev/oprofile/0
    drwxr-xr-x 1 root root 0 15. Nov 12:38 /dev/oprofile/1
    drwxr-xr-x 1 root root 0 15. Nov 12:38 /dev/oprofile/2
    drwxr-xr-x 1 root root 0 15. Nov 12:38 /dev/oprofile/3

    With linux-2.6.19-rc5, the first one (0) is missing and we get 1,2,3

    Maybe the 'bug' is in oprofile tools, that currently expect to find '0'
