Technical Service Bulletin List
Under certain conditions, VP2440 units running coreboot firmware v0.9.0 may experience intermittent network performance degradation on the Intel i226-V Ethernet ports. This issue is related to Active State Power Management (ASPM) states and can cause network throughput to drop significantly below the expected 2.5 Gbps link speed. This issue does not occur with the default AMI BIOS firmware.
A software workaround is available that resolves the issue by disabling ASPM at the operating system level. A permanent firmware fix is currently in development and will be released as soon as comprehensive testing is completed.
