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.
