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?
Nothing exciting on dmesg? Did you check the pci chain to see if
it is being reported as there?
From /var/log/dmesg, when NIC is detected and working:
grep ixgbe dmesg

When NIC is not detected, there is no ixgbe message in dmesg.
I can list irq from dmesg (with NIC detected) and dmesg.old (NIS is not
tedected)

I do not know what you mean "check the pci chain". My knowledge of
kernel level is weak, sorry. What else can I do?
