110 Product Errata
41322 Rev. 3.84 August 2011
Revision Guide for AMD Family 10h Processors
389 HyperTransport™ Link in Retry Mode May Consume Link
Packet Buffer Incorrectly
Description
Under highly specific and detailed internal timing conditions, a coherent HyperTransport™ link in
retry mode that receives an invalid per-packet CRC may cause the processor to incorrectly consume a
link packet buffer during link retry. This erratum applies only when F0x150[11:9]
(HtRetryCrcDatIns) is set to a value other than 000b.
Potential Effect on System
System hang.
Suggested Workaround
When CPUID Fn0000_0001_EAX[7:4] (Model) < 8, no workaround is required. For system
developers that wish to provide a workaround for this event, system software may clear F0x150[11:9]
(HtRetryCrcDatIns) to 000b.
System software should clear F0x150[11:9] (HtRetryCrcDatIns) to 000b for all other affected
processor revisions.
Fix Planned
Yes
