Does this error still occur with more recent kernel versions?

Hello,

I am having lots of trouble with my networking, I am using
RTL-8139/8139C/8139C+ so this concerns 8139too or 8139cp(which by the
way is not working at all). This has been an issue for quite a while,
the last kernel version I can remember not having this issue was 2.6.18
right now I am using 2.6.25-2-686 (the result is the same with 2.6.24) .
It is extremely slow cause lots of packages get droped, it's not even 10
Mbit anymore for downloading, uploading works fine. I will paste the
output of cat /proc/net/dev


eth0:2430459920 1780526 76284 76284 76284 0 0 0
287300795 1386142 0 0 3 0 0 0


As you can see there must be a relation between the fifo and the errors
since fifo , drop and errors are the same number. I am sure it is not an
issue with cables or the switch since I tried lots of different hardware.


I will attach the output of lspci -vvv as a file as well as the output
of lsmod. If there is any further information with wich I can help let
me know.

Unfortunately yes. I tried with 2.6.26-1 and there is no change. It's
still the same with errs drop fifo being the same number of packages.

Can you rule out that it's not hardware-related, e.g. by installing
the Etch kernel package?

Cheers,
Moritz
