--- Comment #13 from Vladislav Shabanov <vlad.shaba...@gmail.com> --- Kevin, thank you for your reply. Changes on this server from March, 2021 till now (October, 2021): 1. Now it’s FreeBSD 13.0 2. On both sides of cable the wire configured to media 100baseTX mediaopt full-duplex. There are no crc errors now, but the problem persists. 3. BIOS has version from 2019.11.02. As far as I understand, all newer versions have patches in CPU microcode, but nothing changed in other parts of the BIOS. However, I will update BIOS in next weeks. 4. The problem persists, hung occurs every couple of days. 5. I added dump for RX Registers, new pair of files attached. With best regargs, Vlad -- You are receiving this mail because: You are the assignee for the bug.
