[Bug 2066064] Re: Dell Latitude 5450 and 5550 Ethernet dropped packets (Intel Meteor Lake CPU with 8086:550a NIC)
Hi Chris, As per this question: https://answers.launchpad.net/ubuntu/+question/816003 I've done some more thorough testing. I have a lot of general Ethernet instability with the Dell 5450/5550 laptops with Ubuntu 24.04 LTS. I also just tried the latest mainline kernel 6.9.1-060901-generic with no luck.

[Bug 2066064] Re: Dell Latitude 5450 and 5550 Ethernet dropped packets (Intel Meteor Lake CPU with 8086:550a NIC)
Hi Chris, Maybe this isn't fixed after all with 24.04 LTS. It just shows differently. Now I'll bring up the wired network with a static IP and just ping it from my PC. It'll randomly stop pinging, I'll see a popup on Ubuntu along the lines of "Connection Failed. Activation of network connection failed." Then ping will stop working for a while. I'll see on Ubuntu that the NIC was disabled and set to Automatic (DHCP) from Manual. If I don't do anything, at some point it's brought back up somehow automatically and ping resumes working again. It's very odd. I'm thinking to test a newer main stream kernel but it's been a while since I did that in Ubuntu.

In addition to disabling the NIC randomly, it is also being changed from Manual to Automatic (DHCP) with no user interaction. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2066064 Title: Dell Latitude 5450 and 5550 Ethernet dropped packets (Intel Meteor Lake CPU with 8086:550a NIC) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2066064/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi Chris, I have a stable ping initially after reboot, however, sometime while using Ubuntu, suddenly the Wired NIC is disabled. If I re-enable it then it's fine again for a few minutes. I think this is a separate issue though. I'll try searching online to see why Ubuntu would randomly disable the NIC on me.

Hi Chris, I just tested Ubuntu 24.04 LTS and I can no longer replicate this issue. I am not familiar with Launchpad bug Status so feel free to close this bug as you see fit.

I asked the following question on the support site as you advised: https://answers.launchpad.net/ubuntu/+question/816003 This is for Desktop. I see that there's now a 24.04 LTS available at this site: https://ubuntu.com/download/desktop I'll download that and give it a try as well. I believe this is a bug with the Linux kernel. Should I raise a bug with kernel.org instead of launchpad.net? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2066064 Title: Dell Latitude 5450 and 5550 Ethernet dropped packets (Intel Meteor Lake CPU with 8086:550a NIC) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2066064/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thank you for taking the time to report this bug and helping to make Ubuntu better. Bug reporting is about finding & fixing problems thus preventing future users from hitting the same bug. I suspect a Support site would be more appropriate, eg. https://answers.launchpad.net/ubuntu. You can also find help with your problem in the support forum of your local Ubuntu community http://loco.ubuntu.com/ or asking at https://askubuntu.com or https://ubuntuforums.org, or for more support options please look at https://discourse.ubuntu.com/t/community-support/709 You've filed this bug against the Ubuntu-Release-Upgrader package, which will upgrade a release from 22.04 to 23.10 (or 24.04 in the future), but no logs or mention of problems with that are mentioned. Ubuntu 22.04 LTS is a LTS release, thus has some kernel stack choices (GA = 5.15, HWE = 6.5, OEM = ...) but no clues as to product (Server? Desktop?) were provided, nor what install media was used (ie. kernel stack defaults are unknown). Your description implies network issues, where bug report is filed against the `do-release-upgrade` (or equivalent) command without logs.. I suggest trying support first.. as your issue maybe more linked to the linux kernel (or kernel modules) and not what you've filed the bug against; but no details as to what you're running were actually provided (release requires product & install media details to be known for LTS releases with kernel stack choice). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2066064 Title: Dell Latitude 5450 and 5550 Ethernet dropped packets (Intel Meteor Lake CPU with 8086:550a NIC) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2066064/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Test script to replicate the bug. Run from another computer connected to the Dell Latitude 5450 or Dell Latitude 5550 over Ethernet. It also requires that SSH be setup so that root can login with passwordless login to the Dell laptops. Note: It doesn't replicate 100% of the time with every reboot. The "try up to 10 times" and "up to 60 ping requests" were chosen arbitrarily. I would expect this test to run overnight without any dropped packets or similarly to be able to ping overnight without any dropped packets. There's no other network devices connected between the two computers. ** Attachment added: "test_reboot_connectivity.sh" https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/2066064/+attachment/5779443/+files/test_reboot_connectivity.sh -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2066064 Title: Dell Latitude 5450 and 5550 Ethernet dropped packets (Intel Meteor Lake CPU with 8086:550a NIC) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/2066064/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
