+          <para>This means that a process is trying to page memory to
+            disk, and the page attempt has hung trying to access the
+            disk for more than 20 seconds.  It might be caused by bad
+            blocks on the disk drive, disk wiring, cables, or any
+            other disk I/O-related hardware.  If the drive itself is
+            actually bad, you will also see disk errors in

+            of <command>dmesg</command>.  Otherwise, check your cables
