Intel
If the ICH6 receives a PCI Express Null packet, it should drop the packet and not perform sequence
number checking or respond with any ACK or NAK DLLP. The ICH6 still performs sequence
number checks for Null packets and may respond with an ACK or NAK depending on the result of
the check.
ICH6 may send ACK or NAK DLLPs in response to a Null packet. This may degrade link
performance due to unnecessary retries.
None.
No Fix. For steppings affected, see the Summary Tables of Changes.
Intel
If the ICH6 receives a DLLP on PCI Express with an unknown encoding type, the ICH6 may
intrepret the packet as an ACK or NAK.
The ICH6 may intrepret the ACK as being from an outstanding TLP sent to the device, indicating
that the device received the TLP. Or, the ICH6 may flag a DLLP protocol error if the sequence
number is not appropriate. If the ICH6 intreprets the packet as a NAK, needless replay may occur.
None.
No Fix. For steppings affected, see the Summary Tables of Changes.
SATA SRST during Link Low Power States
When exiting SATA link partial or slumber states, the ICH6 may not send a SRST when instructed
by software.
The device will not appear available to software until SRST is re-tried.
BIOS workaround available.
No Fix. For steppings affected, see the Summary Tables of Changes.
PCI Express* Replay
The ICH6 PCI Express port’s receiver does not properly recognize a ACK packet from a device
when the ICH6 is replaying a packet.
PCI Express link may halt, resulting in a system hang.
None.
No Fix. For steppings affected, see the Summary Tables of Changes.
This issue has only been replicated using a synthetic test environment using targeted error
injection testing.
