Description ZeroBit 2023-03-06 20:55:34 UTC

The NIC SURECOM EP-320X-S 100/10M Ethernet PCI Adapter stopped to be recognized. It uses driver fealnx which seems deleted from 6.2 kernel

Old kernel 6.1.12 works fine with SURECOM EP-320X-S 100/10M Ethernet PCI Adapter

Sorry, it is my first bug report about the kernel. I don't know what else I should provide

Under old kernel 6.1.12 everything works fine:
$ ethtool -i eth1
driver: fealnx
version: 6.1.12-arch1-1
firmware-version:
expansion-rom-version:
bus-info: 0000:04:03.0
supports-statistics: no
supports-test: no
supports-eeprom-access: no
supports-register-dump: no
supports-priv-flags: no

Under the new kernel  6.2.2 eth1 is absent

The driver had been removed because it had no maintainer and was assumed to be unused.
Can you share more details about your use scenario and deprecation timeline?

Comment 2 ZeroBit 2023-03-07 11:41:01 UTC

Hi, thank you for your answer. The situation I found that bug is very simple. I remotely updated my mother's Archlinux desktop over ssh. And after reboot, it stopped connecting to ethernet. I asked my 69-old mother to show me over the telephone Zoom Network Manager and didn't find the connection. I asked her to do "sudo downgrade linux linux-headers" to the previous kernel and PCI Network Card started to be recognized and system connected to the Internet. That's all. The network card SURECOM EP-320X-S my parents bought in the shop as a brand new card. Now I put packages "linux" and "linux-headers" to the exception for the package manager not to update them. That's all. 

Now I asked her to buy another PCI NIC, now on Realtek chipset for allowing me to update her system without the issues.

I have no idea what you mean under "deprecation timeline". Sorry.

Recently?

> Recently?
I think 3 years ago. The previous stopped working and parents bought absolutely the same.

Comment 5 ZeroBit 2023-03-07 12:09:44 UTC

As far as I remember

Comment 6 Jakub Kicinski 2023-03-07 16:54:05 UTC

Sorry for the trouble, I'll restore the driver upstream (it should probably come back around the 6.2.4 release, it's too late for 6.2.3 I reckon).
FWIW by deprecation I meant when you're planning to replace it. It sounds like you already replaced it with a Realtek card, but if you bought this 3 years ago there may be more of such systems out there.

Comment 7 ZeroBit 2023-03-07 19:08:37 UTC

Thank you very much! 

I asked my mother to buy another NIC. But she at the moment cannot do it. But I prevent the kernel from updating. I hope to wait until 6.2.4 release without changing the NIC. I am sure there are many cards like this all around the world.
