Hi,

here are the ksymoops logs, first oops is kernel BUG at
filemap.c:67! and the second one kernel BUG at page_alloc.c:91!

// Jarno

ksymoops 2.3.4 on i686 2.4.0-test8.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.0-test8/ (default)
     -m /boot/System.map-2.4.0-test8 (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.

Error (regular_file): read_system_map stat /boot/System.map-2.4.0-test8 failed
