[Q]: memory error

Hello,

Our ALPHASTATION 500/333Mhz came from the factory with 128Mb of
memory. I have then added 256Mb for a total of ~384Mb.

It has been working with no problem for about 4 months. For the past
few days I have been getting the attached error message.

Has anyone seen something like this before? I think this is just a
mismatch of the cache registers and the hardware. But is it a problem
with the caching or the board?

With a simple calculation of the EI address, it appears to be on the
226th Mb (maped on the 3rd party added boards).

Any clues or information will be appreciated. I will summarize.

Thank you.
