So I tried an rmmod forcedeth which worked an deactivated eth0.
I've used my wifi connection instead and removed the options nosmp maxcpus=0 I

Hi,
it's quite strange but I removed the forcedeth.ko from
/lib/modules/2.6.28-3-rt/kernel/drivers/net/forcedeth.ko into my home and also
from the 2.6.28-11-generic kernel.
I ran sudo depmod -a
But after a reboot, lsmod appears that the module is still loaded ...

@freyr, @ttoine,
You should do this test:
1) Locate forcedeth.ko (of the 2.6.28-3-rt kernel) module and move it out (in
your home for example)
2) Execute sudo depmod -a
3) Reboot in that kernel
4) Check manually with lsmod that forcedeth.ko isn't loaded.
5) Do all things that you do usually stre
Hi again,
I've found a workaround ... I added the nosmp and maxcpus=0 options to the
kernel (I think both option are equals) ...

Hi,
I can confirm that issue. I got the same behaviour with rt kernel.
It was happening each times I got access to the network when the wifi card and
the ethernet card was both active at the same times.
Since I've deactivated the wifi, it happens sooner or later but later than
before.
