 Posted: Sun Mar 26, 2023 10:02 am Post subject: RTL8125 (2.5Gbps) not detected in AM1H-ITX. |
 |
|
Hi, I need more throughput between my PC and NAS, so I bought two 2.5Gbps PCIe x1 cards to make direct connection between them. First one I put into my PC and it was detected without problem:
| Code: | $ lspci | grep -i net
05:00.0 Ethernet controller: Intel Corporation I211 Gigabit Network Connection (rev 03)
0c:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller (rev 05) |
Second one I put into NAS, but it was not detected. First thought was to check if card is working, so I put it into my PC and both card were detected. Next I put some old dual 1Gbps card into NAS to check if PCIe is working and to my surprise it was detected. Just to be sure, I also check if this card can work in PCIe x16 and it can.
So, now I have working PCIe card that don't want to work in working PCIe slot and zero ideas how to debug it.
PS. I just realized that card is PCIe 2.1, but my NAS has only PCIe 2.0, but from what I found it should still works. |

lekto,
Tell us more about the NAS and why you think a RTL8125 2.5GbE Controller should work there.
The PCIe version is not a problem. Old standards and new standards can be mixed.
The two ends of the link will negotiate a standard.
Exactly what does "detected" mean?
It appears in lspci and works.
It appears in lspci but does not work.
It does not even appear in lspci?

NAS is just mini-ITX PC (AM1H-ITX, Athlon 5350, 8GB of RAM, 3 SSDs and 1 HDD) with Gentoo.
According to my benchmarks HDD in my NAS works with about 180MB/s and SSDs nearly 600MB/s, and since motherboard has only 1Gbps Ethernet I'm only getting fraction of performance.

lekto,
Not appearing in lspci means that that the system cannot read the PCI ID registers.
No drivers are required for that.
Does dmidecode show that the slot is in use?

… and now, after more than 5 plugging/unplugging, card is somehow detected, I wonder for how long.
@EDIT
Worked until reboot.

lekto,
| Code: | | Bus Address: ffff:01:1f.7 |
What does dmidecode say for all the other devices on the PCIe bus?
That ffff in the bus address may be a hint that the kernel needs some encouragement to scan all PCIe busses.

| There are no other devices, this motherboard has only one PCIe x16 slot (mechanically, electrically its x4) and one mini-PCIe for WiFi, which is empty. |

lekto,
Share the output from the NAS please.
It would be good if the 2.5C card was there but if not, no matter.

| I contacted ASRock support, and we came to conclusion that probably motherboard is faulty. I got BIOS that allowed me to forced PCIe generation, NIC was detected for few times in row, then disappeared. I confirmed that card and slot are still working. Now, I could replace motherboard, but I can find used only with included CPU and RAM for more than I’m willing to pay just for knowing. |
