Assuming you are using the 2.6.22-vanilla.series the only patches I see
that were touched between those two were:
      * export-truncate-2.6.18-vanilla.patch in bug 18668
              * remove_from_page_cache(page) ->
                ClearPageMappedToDisk(page);
      * export_symbols-2.6.22-vanilla.patch in also in bug 18668
              * this change is a benign context update
      * i_filter_data.patch in bug 19846
              * benign context update also
      * jbd-commit-timer-no-jiffies-rounding.diff in bug in bug 19321
              * removes rounding of transaction->t_expires when assigned
                to journal->j_commit_timer.expires
      * md-mmp-unplug-dev.patch in bug 17895
              * raid5 fix
      * quota-large-limits-rhel5.patch in bug 19846
              * benign context update

Changes in the actual series were to remove the 8kstack-2.6.12.patch and
add the above mentioned jbd-commit-timer-no-jiffies-rounding.diff.

Given all of this info, I am sure you can figure out how to narrow down
exactly which patch caused the problem.  Please file a bug once you find
it.

Cheers,
b.
