SATA Link Locks Up Under Certain Conditions
Medium
A bug in the SATA core is integrated into the SATA controller.
Due to this bug, under certain conditions, the link locks up between the host and the device and the command times out:
Following cases can bring to these conditions (cases below are not exhaustive):
Use a port reset (COMRESET) instead of a software reset when SATA_PxIS[27] IFS = 0x1 and SATA_PxSERR[23] DIAG_S = 0x1.
Standard software most likely uses port reset rather than a software reset to recover from such an error.
