Subject2.6.0-test3-mm2 kernel BUG at mm/filemap.c:1930
From
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
No ksyms, skipping lsmod
