Hello,
like some have reported before, we also have problems with the e1000
driver and the 82541GI network chips. During the day we have complete
network outages with those chips ranging from some seconds up to a
minute. We have tried different kernels (Base OS is Debian Lenny i686)
and we have tried 2.6.26, 2.6.30 (backports) and 2.6.32 (backports)
kernel images. I have also compiled the latest 8.0.19-NAPI driver for
2.6.30 but the problems persist. We have disabled all offloading
settings for tests but that did not change anything as well. Problems do
not seem to be related to system load or high network traffic, it just
happens randomly. We are seeing this behaviour on different Allnet FW
8888 devices which are equipped with two 82541 ports and three 82572EI
chips. The problems are limited to the 82541 ports, if we switch to the
82572EI ports everything works flawlessly.
I am happy to provide more information.
The following entry appeared in our dmesg today:
