[full build as of Sept. 24] "No route to host" after certain time...

[Rob Lahaye]

Hi,

I have built world and kernel from -STABLE as of today (Sept. 24th).
All seems to work well, but after a certain time (maybe hours, don't
know really), the internet connection breaks.

For example, immediately after boot, everything is okay:

Mozilla connects to whatever, like a charm,
and telnet/ping do as expected:

$ telnet 61.74.111.134 13
Trying 61.74.111.134...
telnet: connect to address 61.74.111.134: Connection refused
telnet: Unable to connect to remote host

$ ping 61.74.111.134
PING 61.74.111.134 (61.74.111.134): 56 data bytes

-------------------------------
then, after a while, when I do the same:

Mozilla gives a dialog with
"connection was refused when attempting to contact foo.bar.com"

$ telnet 61.74.111.134 13
Trying 61.74.111.134...
telnet: connect to address 61.74.111.134: No route to host
telnet: Unable to connect to remote host

$ ping 61.74.111.134
PING 61.74.111.134 (61.74.111.134): 56 data bytes
ping: sendto: No route to host

------------------------------

When I reboot, all is okay again.

Any ideas what has caused this in the new build?
What should I do to investigate further?

See dmesg and uname info below.

Thanks,
Rob.
