I should have stated that the problem is occurring on the 2.5.26 kernel,
NOT 2.4.26.  My mistake.  Also, the hardware is an IBM eServer  8-way x370
with 12GB or RAM, SCSI drives, 2GB swap.  My observation was that not all
memory was being used at the time of the oops and error messages.

I have experienced the following errors while running a test suite (LTP
test suite)  on the 2.5.26 kernel.  Has anybody seen this problem, and, if
so, is there a patch for it?  Please reply directly as I am not yet
subscribed to the mailing list.  Thanks.
