ubuntu ethernet not detected connection in Ubuntu using the console. The cable and connection work fine on other computers, so I'm thinking it's the OS not detecting the port on the computer. I guess you connect through a router to the itnernet.

The dmesg displays the following message: nvidia: probe of 0000:17:00.0 failed with error -1 nvidia: probe of 0000:65:00.0 failed with error -1 Dmesg also displays the following messages indicating that setting up of standard BAR registers for the GPGPUs has failed: pci 0000:17:00.0: BAR 1: no space for [mem size 0x2000000000 64bit pref] pci 0000:17:00.0: BAR 1: failed to assign [mem size 0x2000000000 64bit pref] pci 0000:17:00.0: BAR 0: no space for [mem size 0x01000000] pci 0000:17:00.0: BAR 0: failed to assign [mem size 0x01000000] Workaround Pass pci=realloc=off kernel parameter. Systems affected All Dell EMC PowerEdge systems supporting NVIDIA GPGPUs. Applies to Ubuntu 18.04 and later. Tracking number 203262 A bus fatal error is detected on BCM57XX card Description: Applies to: The operating system and iDRAC reports a bus fatal error on BCM57XX card when the reboot command is issued from the operating system. The error message is due to the driver accessing the device when it is powered off by the shutdown process. This error message can be ignored. Ubuntu 20.04 Known issues 9 Systems affected: All Dell EMC PowerEdge systems with BCM57XX network card. Tracking number: 190284, 190236, 190026, and 190852 Intel E810 and X710-T4L(device id 0x15ff) network cards are not detected after Ubuntu 20.04 is installed Description: Workaround: On installing Ubuntu 20.04, the Intel E810 and X710-T4L(device id 0x15ff) network cards are not detected due to the missing enablement patches in the server generic kernel. The operating system kernel must be updated with HWE kernel with the following command: sudo apt-get install --install-recommends linux-generic-hwe-20.04 Applies to: Ubuntu 20.04 Systems affected: All Dell EMC PowerEdge servers with Intel E810 and X710-T4L(device id 0x15ff) network cards. Tracking number: 190732 Ubuntu deployment through MaaS fails with Broadcom network cards BCM57xx Description: MaaS PXE boot stops responding while loading kernel and initial RAM disk (initrd). This behavior was observed only with the AMD systems with BIOS version 2.0.3. Workaround: Use BIOS version 1.7.4 Applies to: Ubuntu 20.04 Systems affected: All Dell EMC PowerEdge systems with AMD Rome processors. Tracking number: 195848 The name of the NVMe device may change when it is hot-inserted after a surprise removal Description: If an NVMe device is hot inserted after it was previously surprise removed when I/O operations are accessing the device, the name of the NVMe device may change or will not retain the same name that is assigned prior to surprise removal. Dmesg displays the following messages: kernel: nvme nvme3: failed to mark controller CONNECTING kernel: nvme nvme3: Removing after probe failure status: -16 The functionality of the NVMe device is not affected. Applies to: Ubuntu 20.04.01 Systems affected: Dell EMC PowerEdge R740XD, Dell EMC PowerEdge R740XD2 Dell EMC PowerEdge R7525. Tracking number: 181799 10 Known issues NVMe devices are enumerated in namespace 2 when hot-inserted into the server after being surprise removed Description: When an NVMe device from a RAID 1 MD array is hot-inserted after being surprise removed, the device is enumerated in namespace 2 although only one namespace is enabled. The device is named as nvme2n2 instead of nvme2n1. This issue is observed on Dell Express Flash PM1725a device. The functionality of the NVMe device is not affected. Applies to: Ubuntu 20.04.01 Workaround: Pass the multipath=N module parameter to the nvme_core driver. Systems affected: Dell EMC PowerEdge R740XD, Dell EMC PowerEdge R740XD2 Dell EMC PowerEdge R7525. Tracking number: 181814 /proc/mdstat and mdadm -D commands display incorrect statuses when two NVMe devices are surprise removed from a RAID 5 MD array Description: When two of three NVMe devices are surprise removed from a RAID 5 MD array, the command cat/ proc/mdstat displays the array status incorrectly as active. Similarly, when the status of the MD RAID is queried using the mdadm -D /dev/mdNcommand, the number of active and working devices displayed is two. Only the status of the array reported is incorrect. However, when I/O operations are performed, I/O errors are observed as expected. Applies to: Ubuntu 20.04.01 Cause: When the number of devices that are surprise removed exceeds the number of devices that are required for the array to function, the MD status is not updated. Systems affected: All Dell EMC PowerEdge systems Tracking number: 182820 Status of the RAID 0 LV is displayed as Available when one of the members of the RAID array is surprise removed Description: When Logical Volume Manager (LVM) is used to create a RAID 0 array and a member of the RAID array is surprise removed, the lvdisplay command shows the LV status as Available. Applies to: Ubuntu 20.04.01 Solution: Use the command lvs -o +lv_health_status to check the status of the RAID array. The command displays the output Partial when a member of the RAID array is removed. Systems affected: All Dell EMC PowerEdge systems Tracking number: 175865 Known issues 11 BIOS Dell Update Packages (DUPs) will not run on Ubuntu 20.04 Description When the operating system DUP method is used to update the system BIOS, the firmware update fails to run on Dell EMC PowerEdge R240, R340, T140, T340 severs. Cause This issue is specific to Intel Mehlow platforms where the Intel MEI driver is causing the firmware update from running. Workaround Perform the firmware updates through iDRAC or Lifecycle Controller (LC). Excluding the Intel MEI and mei_me drivers allows the BIOS DUP to function. Systems affected Dell EMC PowerEdge R240, R340, T140, T340 severs. Applies to Ubuntu 20.04 Tracking number 178459 Ubuntu Server 20.04 live image installation fails due to a loss of network connectivity Description The Ubuntu Server 20.04 live image installation fails due to a loss of network connectivity. The live image is designed to update all the packages to the latest version and then proceed with installation. Solution For seamless installation of Ubuntu Server 20.04, at least one network connection is required. Systems affected All yx4x and yx5x Dell EMC PowerEdge servers. Applies to Ubuntu 20.04 Tracking number 168103 CCP initialization failed error encountered after Ubuntu.20.04 is installed Description The following error message is displayed after Ubuntu 20.04 is installed: ccp initialization failed Functionality of the operating system is not affected, and the error message can be ignored. Cause The CCP engine is disabled in the system BIOS. The operating system recognizes the CCP engine however, it is not initialized. Systems affected All yx4x and yx5x Dell EMC PowerEdge servers. Applies to Ubuntu 20.04 Tracking number 169087 NVMe drive is not detected after multiple hot plug operations Description Cause NVMe drive is not detected when multiple hot plug operations are performed. A race condition that is related to MSI interrupts and their handling in the pciehp driver interrupt service routine causes this issue. 12 Known issues Workaround 1. Read the Slot Status Register in the PCI Express Capability structure by running the following command: setpci -s e0:03.2 CAP_EXP+0x1a.w Output: 0148 (value returned) 2. Clear the event bits that are impacted by running the following command: setpci -s e0:03.2 CAP_EXP+0x1a.w=0x0108 3. Read the Slot Status Register again to confirm that event bits are cleared by running the following command: setpci -s e0:03.2 CAP_EXP+0x1a.w Output: 0040 (value returned) 4. Unplug the drive and then plug-in the drive after clearing the event bits. Systems affected All yx4x and yx5x Dell EMC PowerEdge servers.
