[Bug 2141531] Re: Network unstable on 6.8.0-100.100

Hi Tim,

Its great to hear that 6.8.0-103-generic seems to have fixed your
problem.

I went and had a look at all the changes in -103, and there was 192 patches
just for networking only, out of 2114 total patches.... maybe your problem was
the same as that other bug, maybe it wasn't and another patch fixed it instead.

ubuntu-noble$ git log --oneline Ubuntu-6.8.0-100.100..Ubuntu-6.8.0-103.103 net/ | wc -l
192
ubuntu-noble$ git log --oneline Ubuntu-6.8.0-100.100..Ubuntu-6.8.0-103.103 | wc -l
2114

Full list if you happen to be curious (networking changes in 103):
https://paste.ubuntu.com/p/TsZcJ7qFKw/

There seems to be quite a few people experiencing networking problems in -100,
so I think I will go speak to the Kernel Team and see if they will possibly
consider releasing -103 a little earlier than the week of 9th March.

Anyway, you can keep using -103, it will be the next noble kernel once the
2026.02.09 SRU cycle completes.

Thanks,
Matthew

Title:
Network unstable on 6.8.0-100.100

Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Noble:
Fix Committed

Bug description:
Ever since this upgrade was installed the network has been unstable.
Doing network speed tests the uploads almost always fail, often quoted
a socket error.

6.8.0-94 works fine. A DFNS check worked fine, but fails on -100.

Another windows PC on the same network works fine. ISP says all is
good.

I am on Ubuntu 24.04.3 LTS


I have reported via ubuntu-bug linux, which I had to rune twice due to network issues, but I think it still failed:
