Hello,

We have some known issues with 82574L but most have been resolved in the latest versions, so I'll need some more information.

What version of e1000e are you using exactly?  Are you able to download and test the latest version of the driver from SourceForge?
  
Please open an issue at SourceForge.net for easier tracking of debugging information.

Please provide an output of lspci -vvv.

What hw platform is this happening on?  How often does it happen and how long does it take to happen after reset or reboot?  Is ASPM enabled or disabled on your system.  Its possible to disable this in the BIOS, but not all BIOS provide the option.  If its enabled for some reason, please disable it and try the driver again.

Thanks,

Carolyn
