NOTE: It is really bad behaviour to post the same  question  indepen-
dently  in  several  mailing  list.  Your  question  has already been
answered on the ELDK list.

And this strange "internal limit"  is  an  indication  that  you  are
running code that is more than 1.5 years old, as the bug was fixed in
September  2006.  It was caused by bad PCI mappings that overlap with
CONFIG_TASKSIZE.
