Got this while trying to mount the rootfs.  It was ext3 if that makes
any diff.  

ksymoops 2.4.8 on i686 2.6.0-test3-mm1.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.6.0-test3-mm1/ (default)
     -m /usr/src/2.5/linux-2.6.0-test2/System.map (specified)

Error (regular_file): read_ksyms stat /proc/ksyms failed
No modules in ksyms, skipping objects
