Product Errata 119
Revision Guide for AMD Family 10h Processors

405 HyperTransport™ Link May Fail to Complete Training
Description
HyperTransport™ links may fail to re-train when resuming from LS2 low-power mode or following a
warm reset. The failure may be package-specific and sensitive to longer HyperTransport links that
contain multiple connectors.
Potential Effect on System
System hang.
Suggested Workaround
On G34r1 and C32r1 processors, system software should program the Link Global Extended
Register[RXCalEn] (F0x16C[9]) to 1b.
For Fr5 (1207) and Fr6 (1207) processors, system developers that observe the erratum conditions
following warm reset should program the Link Global Extended Register[RXCalEn] (F0x16C[9]) to
1b.
For all other processors, system software may program the Link Global Extended Register[RXCalEn]
(F0x16C[9]) to 1b. This workaround is not necessary if erratum #351 applies to the processor
revision.
Fix Planned
No
