Are you saying you can cause correctable errors on demand?  How?

If these are single-bit memory errors being corrected by ECC,
you likely have a DRAM going bad or possibly a bad connection.
If possible, it is useful to have the location logged so that
you can reseat/replace the bad memory chip/SIMM/board/whatever before
you get a double-bit error and panic.  This isn't necessarily something
you want output to the console, unless that's the only option.

Perhaps the "machine panic" is a double bit (uncorrectable) error?
