I'm glad to see this thread; I have a different error, for which I wanted to make sure I was fixing the right problem before randomly swapping hardware. > John Baldwin tends to keep up-to-date patches for mcelog here: > > http://people.freebsd.org/~jhb/mcelog/ > > The last build of mcelog I did on FreeBSD was for mcelog-1.0pre2, which > John's patch (at the time) did not work with.

I found one additional intermediate patch from John, posted on 2011-04-26, that appears to have not been merged into ~jhb/mcelog/ : http://lists.freebsd.org/pipermail/freebsd-hackers/2011-April/035159.html That patch got me up and going (using 'gmake FREEBSD=yes i386=yes') My problem is different from the original poster; looks a bit more serious: royce@heffalump$ ./mcelog --no-dmi --ascii MCA: Bank 1, Status 0x9400000000000151 MCA: Global Cap 0x0000000000000105, Status 0x0000000000000000 MCA: Vendor "AuthenticAMD", ID 0xfc0, APIC ID 0 MCA: CPU 0 COR ICACHE L1 IRD error MCA: Address 0xc089d890 HARDWARE ERROR.

The same goes for git.kernel.org. Great..... kernel.org is still down from the compromise a few weeks ago. At least one kernel.org mirror still has mcelog-1.0pre2: http://mirror.xmission.com/kernel.org/linux/utils/cpu/mce/mcelog-1.0pre2.tar.gz The main mcelog page also has a link to how to get it from GitHub while kernel.org is down: https://github.com/andikleen/mcelog Agreed that a port and a CGI would be higher leverage, but these breadcrumbs should help in the short term.
