Public bug reported: I work with the company that has obtained 300 used Dell Latitude 5420 laptops. They ware running Windows previously without problems. However under Ubuntu (22.04; 24.10) there is a problem with Intel i219-LM (13) NIC. Kernel module e1000e on load performs NVM checksum validation and fails. Tested sample suggests about 70% of laptops are affected.
I modified e1000e module to bypass checksum and after that NIC works as it supposed to. I tried to correct NVM using ethtool and intel provided tool but it seems Dell locked writing to NVM on these laptops. I searched internet and this is not the first time this problem has occurred. There even used to be a patch adding module parameter to force checksum bypass (https://patchwork.ozlabs.org/project/ubuntu- kernel/patch/[email protected]/#470600). I wonder why ubuntu kernel is no longer shipped with this patch? Can you add this patch back or similar workaround? ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2102113 Title: intel i219-LM on Dell 5420 with bad NVM checksum doesn't work with e1000e driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2102113/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
