My Gigabyte Gaming X AX motherboard with a Realtek R8125 Ethernet chip and running Linux is disconnecting from the LAN after exactly one hour, as in 3600 seconds. This was determined by starting a ping at the rate of once every second from another machine aimed the Realtek Ethernet port and noting the time it first responded to a ping after a reboot, until it went off line. During a recent test, the first response in epoch time was at 1700049024.189512 or 11:50:24.189 UTC and the last response was at 1700052623.549328 or 12:50:23.549

After it goes off line there is nothing you can do externally or from the console to bring it back up. The only solution noted so far is to reboot. It appears there is some sort of timeout that is occurring. The driver I am using is a Realtek r8125 v: 9.012.03 issued Oct 31, 2023.

Has anyone else experienced this problem and possibly found a solution? Having to reboot once an hour is not acceptable.

Response from the Linux command “inxi -N -v 7” shows the following

Device-2: Realtek RTL8125 2.5GbE vendor: Gigabyte driver: r8125 v: 9.012.03-NAPI pcie:

You will need to narrow down the chipset for the motherboard. As of this writing, I count (at least)4 motherboard's from Gigabyte under the Gaming X AX nomenclature.

What BIOS version are you currently on for your motherboard?
 
I am killing this thread. I have repeated my test using ping on a fresh install with nothing added, not even a desktop GUI, and I am now up to 70 minutes and there is no sign of a disconnect. It appears it is related to the software I installed in setting up this machine up as a mail server for my domain using sendmail, dkim, etc. I will have to repeat my install sequence with frequent tests between each step to figure out where the problem occurs. Thanks for your patience.
