Are you running anything that may use VT-x (e.g. VirtualBox, bhyve) on this machine? >From my kernel log: ----8<---- CPU: Intel(R) Xeon(R) CPU E3-1245 v3 @ 3.40GHz (3392.50-MHz K8-class CPU) Origin = "GenuineIntel" Id = 0x306c3 Family = 0x6 Model = 0x3c Stepping = 3 [...] MCA: Bank 0, Status 0x90000040000f0005 MCA: Global Cap 0x0000000000000c09, Status 0x0000000000000000 MCA: Vendor "GenuineIntel", ID 0x306c3, APIC ID 6 MCA: CPU 6 COR (1) internal parity error MCA: Bank 0, Status 0x90000040000f0005 MCA: Global Cap 0x0000000000000c09, Status 0x0000000000000000 MCA: Vendor "GenuineIntel", ID 0x306c3, APIC ID 6 MCA: CPU 6 COR (1) internal parity error ----8<---- This only happens when I'm running a VM in VirtualBox; regardless, the machine is rock solid. My research leads me to believe it's a bug in Haswell's VT-x implementation. -- Fuzzy love, -CyberLeo Technical Administrator CyberLeo.Net Webhosting http://www.CyberLeo.Net <CyberLeo@CyberLeo.Net> Furry Peace! - http://www.fur.com/peace/
