>From the reports I have heard on this list for this problem, it was
special IO caused by certain types of writes that occur mainly in the
ext3 fileystem(may be old info).  Has anyone had better success using
reiserfs, JFS, or XFS?  I know none of these are there for Redhat users
by default but what about other distros?  I am looking at upgrading a
Redhat 7.3 PE 2650 and have been dreading it due to the problems
mentioned on this list.  It will be running Debian (Sarge) with a 2.6.x
