I've been having a very annoying issue with an 82574L for a pretty long time now.
After the PC is turned off (either properly or due to a power failure), the NIC does not work upon the next boot. em0 at pci1 dev 0 function 0 "Intel PRO/1000 MT (82574L)" rev 0x00: msiem0: The EEPROM Checksum Is Not Valid em0: Unable to initialize the hardware I found an Intel firmware flashing utility for DOS that rebuilds the checksum. After running it, however, my MAC is 00:00:00:00:00:00. I need to set the mac back with it, and make it rebuild the checksum. After I do this, OpenBSD boots fine: em0 at pci1 dev 0 function 0 "Intel PRO/1000 MT (82574L)" rev 0x00: msi, address 00:22:4d:7c:b2:76 The NIC is an onboard one, and I've no extra PCI slots, so I can't really change it. Here's my full dmesg in case it's of further use. Please also let me know if there's anything else which may be of use.
