Opened: Jan 04, 2025 Severity: 2-Critical
Datapath lockup in the ATSE FPGA. Can be seen at startup with no traffic received at the host, or some time after startup with packet framing errors. This can also show up as a transmit packet path lockup because health check loopback packets can back up into the transmit datapath and block it.
The impact is no packets can get from the network to host for processing.
No known conditions.
The datapath lockup requires a reload of the ATSE FPGA. Reload typically done by rebooting the system. This issue has been fixed in ATSE bitfiles v72.5.8.00 and v72.41.8.0 and all newer bitfiles.
