Revision Guide for AMD Family 10h Processors

354 HyperTransport™ Link Training Failure
Description
Some processors may fail HyperTransport™ link training at speeds greater than 2.0 GT/s. The link
training failure may be intermittent.
Potential Effect on System
When exiting from S3, S4 or S5 state, the system may hang when a reset or LDTSTOP is applied and
the link speed is greater than 2.0 GT/s. In addition, when F0x[18C:170][Ls2En] is set the system may
hang exiting from LS2 link power state if the link speed is greater than 2.0 GT/s.
Suggested Workaround
System software should set bit 6 of F4x1[9C,94,8C,84]_x[58:50, 48:40] for all links. The bits should
be set before the link frequency is changed from the cold reset value.
Fix Planned
Yes
