Updates to Intrepid has fixed this problem! No more irqpoll workaround
is needed on boot :)

Status: Confirmed = Fix Released

Unfortunately the problem has proven to replicate itself in Intrepid. I
even tried a different router to see if that fixed it, but it did not. I
am certain this is a software error.
Running the kernel option of irqpoll appears to prevent the bug from
occuring however.

To report on some additional findings:
1. I compiled a vanilla 2.6.25.8 kernel and the problem was replicated
2. I upgraded to Intrepid pre-alpha, and I am very pleased to report that the
problem no longer occurs. I dont know if it is due to new ACPI / ACPID or
kernel changes though.
I intend
So I have been doing more research and I think Im narrowing it down now.
In summary I think:
After a period of no network use, ACPI thinks IRQ 23 isnt needed
ACPI turns off IRQ 23
eth0 times out and wont come back without reboot
ifdown/ifup wont fix it

Thankyou for Cappy for the advice. I have triple checked your
instructions and its my displeasure to advise that does not fix it. Also
while doing this, I observed that it too far longer for the default
gateway to come back from the route command - maybe it was auto adding
itself?. Worse, I was
This can be fixed by running:
gksudo gedit /etc/default/acpi-support
and changing the line
STOP_SERVICES=
to
STOP_SERVICES=networking
Then save the file.

Instead of rebooting, have you tried just reloading the kernel module?
I.e
sudo rmmod e1000
sudo modprobe e1000

Thanks for the suggestion Erik :)
Ok so I figured out Ive got a Via Rhine II VT6102 version 7c ethernet
nic. Apparently that uses the via-rhine module. So I did my fast way of
testing this instead of having to wait for it to sleep:

I thought this bug thread was dead. I posted a solution some time ago:
http://www.mcdb.ucla.edu/research/hartenstein/acardona/ubuntu_tips.html#Fixing%20the%20disappearing%20ethernet%20network%20interface%20for%20Thinkpads
.. which says:
sudo modprobe -r e1000
sudo modprobe e1000
sudo idown eth0
Albert this problem is not isolated to your hardware. I dont have an
Intel Pro 1000 nic, Ive got a Via RHINE II nic (via-rhine). Anyway I
tried the workaround Erik suggested which youve also suggested, and it
does not fix the problem. So far the only solution is a reboot which is

Ok, finally I have managed to find an obscure workaround to this
frustrating bug. Please note, this is not a fix, and it requires manual
commandline intervention which is not supportive of the it just works

I can confirm this bug exists on Hardy Heron AMD64. In my view, this is
a critical issue preventing me from having a quality experience on
Ubuntu. I have spent alot of time puzzling over this bug and testing out
various things. I have now exhausted all possible avenues I know how to
do myself and
This bug is still present as of today, with 7.04 dist-upgraded to the
latest.
Is there any partial cure? For example, is there anyway to reload the
proper network kernel modules, for instance, that may fix the problem?
