Ok, that 0x12 looks like it fits the TlbCacheDis thing (bits [5:1]):


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 [Determining The Access Destination for CPU Accesses]."


Good mailing practices for 400: avoid top-posting and trim the reply.
