    In 2.6.9-test9 (also tried with bk15) I have ext2 and ext3 both
    configured as modules. When I do "modprobe ext3" it says:

      FATAL: Error inserting ext3
    (/lib/modules/2.6.0-test9-bug-t1/kernel/fs/ext3/ext3.ko): Unknown symbol
    in module, or unknown parameter (see dmesg)

    and dmesg says:

      ext3: Unknown symbol percpu_counter_mod

    I found one message in the archive
    (http://www.ussg.iu.edu/hypermail/linux/kernel/0310.2/0311.html) which
    mentions this problem and includes a proposed fix. The lines from the
    this proposal made it into lib/percpu_counter.c but somehow it seems
    that they are not causing the symbol to end up in the main kernel
    image. In fact the string "percpu_counter_mod" does not occur in
    vmlinux or in any of the modules other than ext2.ko and ext3.ko.

    The kernel in question was compiled with gcc 3.3.1 on an up-to-date
    debian/unstable. A copy of the exact .config I used can be had from
    http://jlb.changelog.com/config-2.6.0-test9-bug-t1
