Hi there,

I don't quite believe in that -- when running the same machine under
OpenBSD, things worked well...

Do you know what FreeBSD does when an ECC error is encountered? Does it log
it? Does it just silently discard the information? Can the kernel know about
ECC corrective actions at all? I have no clue of all that... Another
information I'd be happy to get :-)

Cheers,
  Thiemo
