Kernel r8169 driver is broken.

SUSE Linux Enterprise Desktop
1

I do have a fix for it, BUT it needs kernel module to be compiled by someone.

Then a reload cycle for the module is needed.

See https://lja.fi/lja/wordpress/index.php/linux-kernel-r8169-network-driver-fixup/ for patch.

@Lauri Hi and welcome to the Forum :slight_smile:
Sometimes it can be a conflict between 8168 and 8169 driver can you provide info in the card;

/sbin/lspci -nnk | egrep -A3 "Net|Eth"

00:1f.6 Ethernet controller [0200]: Intel Corporation Ethernet Connection (10) I219-V [8086:0d4f]
        DeviceName:  LAN
        Subsystem: Intel Corporation Ethernet Connection (10) I219-V [8086:2081]

        Kernel modules: e1000e
01:00.0 Non-Volatile memory controller [0108]: Intel Corporation Device [8086:faf0] (rev 03)

The patch I provided makes the driver work, when reloaded.

Wrong NIC info

@Lauri Hi and what release of SLED and kernel is in use?

cat /etc/os-release
uname -a
7

Latest desktop release, the bug is not linux-installation specific.

@Lauri Hi, then will be very hard to fix AND ensure the system is supported, performing your patch will void any support, it would be better to raise a support request to get a supported fix.
