I have a Dell Latitude 5420 laptop with LMDE, running kernel 6.1.0-12. This laptop has a builtin I219-LM ethernet controller that I can see via lspci. Some research indicates that this needs the e1000e kernel module, so I grabbed it from Intel, compiled it, and installed it. There were some complaints during the compilation, but nothing more than the average compilation process. Plus, it shows up in lsmod. Afterwards, lspci -vv displays it with the e1000e driver:

0000:00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection (13) I219-LM (rev 20)
        Subsystem: Dell Ethernet Connection (13) I219-LM

                Address: 0000000000000000  Data: 0000
        Kernel modules: e1000e

However, when I do lshw, it is listed as unclaimed:

  *-network:1 UNCLAIMED  
       description: Ethernet controller  
       product: Ethernet Connection (13) I219-LM  
       vendor: Intel Corporation  
       physical id: 1f.6

       capabilities: pm msi cap_list  
       configuration: latency=0  
       resources: memory:a6100000-a611ffff

…and of course, it’s still not showing in ifconfig. So, where do I go from here? Did I miss anything obvious?

And just for the record, I know that the ethernet port is working. It worked fine in Win11 before wiped the PC completely.

      Pretty much when you posted that, I found this in my dmesg:

      [  715.744332] e1000e 0000:00:1f.6: Interrupt Throttling Rate (ints/sec) set to dynamic conservative mode
[  715.965683] e1000e 0000:00:1f.6: The NVM Checksum Is Not Valid
[  716.008541] e1000e: probe of 0000:00:1f.6 failed with error -5

      Just for the record, I compared modinfo up against lspci, and the PCI ID matches, so the driver should work. Is it possible to ignore the NVM checksum and try anyway? Because any tool I can find that communicates with the EEPROM on a hardware level is made for msdos.

        Unfortunately this is uncharted territory for me. I did a quick web search though, and you aren’t alone. At least a few people have had the same problem before.
