Recently there were a few stories published, based on a blog post by an end-user, suggesting specific network packets may cause the Intel® 82574L Gigabit Ethernet Controller to become unresponsive until corrected by a full platform power cycle.
Intel was made aware of this issue in September 2012 by the blogs author. Intel worked with the author as well as the original motherboard manufacturer to investigate and determine root cause. Intel root caused the issue to the specific vendor’s mother board design where an incorrect EEPROM image was programmed during manufacturing. We communicated the findings and recommended corrections to the motherboard manufacturer.
It is Intel’s belief that this is an implementation issue isolated to a specific manufacturer, not a design problem with the Intel 82574L Gigabit Ethernet controller. Intel has not observed this issue with any implementations which follow Intel’s published design guidelines. Intel recommends contacting your motherboard manufacturer if you have continued concerns or questions whether your products are impacted.-
