Critical Issue
Description
The Stratix® 10 L-Tile Hard IP for PCI Express® core configured in Gen3 mode may undergo several Recovery cycles when changing speed to Gen3. After a few Recovery cycles, the link stabilizes in the L0 state. Initial link up to Gen3 is not affected. The Recovery cycles only occur in subsequent speed changes after initial link training to Gen3.
Resolution
This issue is not fixed in L-Tile.
