Ok, that 0x12 looks like it fits the TlbCacheDis thing (bits [5:1]): "0_1001b Link: A specific coherent-only packet from a CPU was issued to an IO link. This may be caused by software which addresses page table structures in a memory type other than cacheable WB-DRAM without properly configuring MSRC001_0015[TlbCacheDis]. This may occur, for example, when page table structure addresses are above top of memory. In such cases, the NB will generate an MCE if it sees a mismatch between the memory operation generated by the core and the link type. See 2.9.3.1.2 [Determining The Access Destination for CPU Accesses]." -- Regards/Gruss, Boris. Good mailing practices for 400: avoid top-posting and trim the reply.
