en_poismsg_spec_behavior:
A received poison packet is treated as a Fatal error if its severity bit is set, 
but treated as a correctable if the severity bit is cleared and logged in both 
the UNCERRSTS register and the Advisory Non-Fatal Error bit in the 
CORERRSTS register.
In Intel Xeon processor E7-2800/4800/8800 v2 product family Product 
Family B0 stepping, a POISFEN bit forces the poison error to be logged as 
an Advisory Non-Fatal error. When this bit is set, the poison severity bit can 
force Fatal behavior regardless of POISFEN. Generally, however, MCA needs 
to have priority over AER drivers, so this bit default is 0. Note that the 
PCIe* spec requires this bit to be 0.
When this bit is clear:
sev pfen 
error
0 0 non-fatal
0 1 correctable
1 0 fatal
1 1 correctable
When this bit is set:
sev pfen 
error
0 0 non-fatal
0 1 correctable
1 0 fatal
1 1 fatal

poisfen:
Enables poisoned data received inbound (either inbound posted data or 
completions for outbound reads that have poisoned data) to be forwarded 
to the destination (DRAM or Cache or PCIe* Peer).
0: Poison indication is not forwarded with the data
(this may result in silent corruption if AER poison reporting is disabled.)
1: Poison indication is forwarded with the data
(this may result in a conflict with MCA poison reporting if AER poison 
reporting is enabled)
