Make sure you test your code on a Rioworks HDAMA-based AMD64 if you get the chance. I turned on MCE on our 2.4.25 Linux i386 kernels and they trapped during the boot. Apparently there's something goofy with that board (or Opteron 244 processors?) and MCE. -- Doug White | FreeBSD: The Power to Serve dwhite@gumbysoft.com | www.FreeBSD.org _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org"
