I am running into the same BSOD issue with my SR2 as well.
I am running Windows 7 64-bit and the following;
5680 6 Core Cpus
32 GB OCZ Ram 10666
2WD 1TB 64MB Cache (Black) both raid 0 on marvel controller
2 BFG GTX 280s
and a X-Connect 1600 Watt PSU to power the system.
I am mainly using the rig for VMware Infrastracture purposes but I am getting rather displeased with the system locking up and killing all of my VMware enviorments due to a unstable hardware enviorment BSOD.
Hence the following information I have found as well;
Chip Number: .Vendor ID 0x8086
Chip Description: Intel(R) Active Management Technology - Serial Over LAN (SOL)
Notes: Driver is included with Intel Management Engine Interface driver
When i search for "Vendor ID:Device ID: 0x8086:0x3406" i found that it is a Intel Device but not what for a device it is.
Device "Intel(R) 5520/5500/X58 I/O Hub to ESI Port - 3406".
Since this happens every so often or.. two times tonight now, I am not sure if this board is ready for a steady VMware enviorment as there is no way I can trust this system in production.
Is there any hopes on the horizion for some sort of system stability through a BIOS update or a Driver fix?????
p.s. Yes I have been asked why I would ever need this kind of power for gaming... and I usually say that this board is the perfect VM solution for both ESXI and Server but I am starting to have my doubts.
