Its probably a SA problem with the source as Doomer says

Yes, but you really should fix the problem with your chip reader. It appears to be dropping 32-bit dwords (not 16-bit words as I previously wrote).

If it is anything like the MRT Lab problem that I was working on some time ago, I suspect that your reader may be communicating with your computer via a 32-bit bus. If so, then the corruption would be consistent with a buffer overrun problem, possibly due to slow interrupt servicing.
