#89627 — Bug#1111011: Acknowledgement (RTL8125D - link drops)

Tested kernels 6.15.3 and 6.17.2 too - same problem.
It has something to do with switch and/or 100Mbit vs 1Gbit:
- 1Gbit switch #3 - STABLE!!!
- 100Mbit switch #1 - drop every 90-130s
- 100Mbit switch #2 - drop every 27-28s

Does

	ethtool --set-eee eth0 eee off

help operating the device at 1 Gbps?

Right now I'm wondering if it might relate to
https://git.kernel.org/linus/bf7154ffb1c65a201906296a9d3eb22e9daa5ffc 

If so you might want to try the 6.18 kernel in experimental. The
commit is as well included in the upcoming 6.17.8-1 upload to
unstable.

Salvatore

Okay too bad. There was a second question in my email:

If so you might want to try the 6.18 kernel in experimental. The
commit is as well included in the upcoming 6.17.8-1 upload to
unstable.

Please test the most recent versions in unstable and experimental, so
we might get a picture if it can be reported upstream.

Regards,
Salvatore
