Tracking number: 155501, 155503
When booting the system from iSCSI with Mellanox
CX-4 and CX-5 adapters, the system reports csum
failure message
Description: When booting the system from iSCSI with Mellanox CX-4 and CX-5 adapters, the following message is
displayed in the dmesg and /var/log/messages reports:
localhost kernel: ibft0: hw csum failure
This message can be ignored.
Applies to:
SUSE Linux Enterprise Server 15 SP1
Cause: Some networking switches which are sending frames with nonzero padding bytes maybe causing the
issue.
Workaround: Install out-of-box drivers.
Solution: The issue is resolved in SUSE Linux Enterprise Server 15 SP2
Systems
affected:
All Dell EMC PowerEdge systems
Tracking number: 156922
Linux operating system fails to detect the Intel x710
card
Description:
The i40e in-box driver is not enabled to detect an Intel x710 NIC. NIC details can be identified by running
the command lspci.
The output of the command is as follows:
Ethernet controller: Intel Corporation Ethernet Controller x710 for 10GBASE-T
Vendor ID: 8086
Device ID: 15FF
The following installation kit from SUSE Linux Enterprise Server can be used for network-based
deployments in systems with Intel x710 NIC: Dell EMC PowerEdge Installation Kit.
Applies to:
SUSE Linux Enterprise Server 15 SP1
Cause: The i40e in-box driver is not enabled to detect an Intel x710 NIC.
Workaround: Install the out-of-box drivers.
Solution: The issue is resolved in SUSE Linux Enterprise Server 15 SP2, SUSE Linux Enterprise Server 15 SP1
Maintenance Update kernel-default-4.12.14-197.29.1 version and later.
