Hi, We 64 identical machines here for now I only tried to boot coreboot on 11 of them where 4 of them got this early hang. I switched the bootstrap processor from a machine that fails and put it into one that always boots with coreboot, now the machine which was failing before now boots perfectly and the other fails. Conclusion: Its the CPU!!
All machines here came with the B2 revision of the Opteron 8350 which has this weird TLB failure but we also have B3 revision processors here, so I installed a newer one and coreboot refuses to boot as well! :( So the question is what could possibly be the difference between an Opteron 8350 B2 and another Opteron 8350 B2? I started to dump registers, and I'm not done yet, but so far they are all identical.
