If you have ext3 filesystems active on the same box then a bug in
ext3 can actually prevent kernel threads from flushing anything else
to disk. This is fixed in the latest 2.4.21-pre kernel, but not a
lot of other places. If folks are running with ext3 in the mix this
may be the cause of the problem.
