Hi Firmware,

Thank you for posting in Wired Communities. Just to double check:1) Was there any changes made on the system recently? 2) Have you tried changing the cable to test? 3) What is the brand and model of the system where the 82574L is embedded?4) Can you check if this command will work for you by configuring IntMode=1,1, you may refer to this link about the issue of 82574L https://communities.intel.com/thread/117293 https://communities.intel.com/thread/117293 Please feel free to update me.Thanks,Sharon T
