Hi,
I got the following OOPS while doing some heavy compilations (make -j4) on dual SMP
P-III,
2.4.0-test10-pre5 and reiserfs 3.6.18 for 2.4.0-test9.
It looks like page without page->mapping has been passed to
block_read_full_page().
Unable to handle kernel NULL pointer dereference at virtual address 00000010
