Reason for TEA machine check exception

I am using a custom MPC8248 board running Linux 2.4.  I occasionally get a
machine check exception when trying to read from an address that should be
mapped to PCI space.  The reason is supposedly a transfer error acknowledge
(SRR1=41030).  As far as I can tell from the 8272 reference maual, this means
that the !TEA signal was asserted during the bus cycle, but on this board that
pin is pulled up to VCC.  Is there some other condition that causes a TEA
machine check?

Thanks in advance.

Mike
