I have brand new PC with this components:
CPU Intel® Pentium G5400, LGA1151
motherboard ASUS PRIME B360M-C
16 GB RAM
HDD 2x ADATA SSD 256GB XPG GAMMIX S11, PCIe Gen3x4 M.2 2280 (RAID1)
NIC Intel X550-T1 Ethernet Converged Network Adapter

I installed CentOS 7 and two NICs were detected:
eno1 (on motherboard)
enp1s0 (Intel X550-T1)

When I restart the machine sometimes enp1s0 is missing. It is not detected during boot. It looks like NIC card is not installed / not present. After next reboot everything is fine and I do not see any problems with NIC card.

How can I avoid this problem with missing NIC? Can you help me, please?


Hallo,
perhaps a timing problem until the nic is up or a bios bug.
