Hi Juergh, Thanks for responding, yes, I visited this link: ttps://www.broadcom.com/products/ethernet-connectivity/network- adapters/bcm57416-1gbase-t-ic
Before submitting this bug report, and there are only drivers available for BSD and Windows. About firmware section, I see there could be a potential fix for this issue or maybe not. I'll update later. About the bug reporting guidelines: I apologise for coming un-prepared, I'll upload, and update requested logs/files soon. Below are the things I have tried so far: 1) After upgrade from Ubuntu 22.04 LTS to 24.04.2 LTS issue appeared with generic kernel and then with RT kernel too. 2) We tried fresh install of Ubuntu 24.04.2 LTS, issue didn't appear. Then we installed RT Kernel and setup isolated cores with TuneD. Issue started appearing. Also, there is another issue started coming with TunedD, at server stuck while reboot, we have to turn off and on. Will report this separately, in case some of you know this I'd appreciate if you can comment. Thanks again everyone for taking time to look into.

Post upgrade to Ubuntu 24.04.2 LTS we observe that whenever we try to download something below message appears on screen: bnxt_en 0000:4b:00.1 ens3f1np1: NIC Link is Down After this file download is stuck, and NIC comes up in a few seconds, and file transfer resumes. After few seconds again (sometime after a minute or so), same message appears again. And again, we observe that NIC has come up, but it never gets IP (no DHCP Discover, or any communication is seen outwards). We tried assigning manual IP still we cannot reach it. It seems, firmware itself is doing some problem and physical communication breaks in link level. Nothing is seen in kernel logs other than NIC down and up events. I'll attach output screenshots anyway. Also, in logs you will see that I'm using RT Kernel, but it was coming consistently on generic kernel too, post that we upgraded to RT for our work. We tried searching, firmware/driver updates for this, on Broadcom website, but there isn't none. It seems Linux firmware needs update.
