Lenny + CS20 Network Weirdness (e100)
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
First, my apologies if this has actually been discussed and resolved
somewhere. I have found *lots* of similar issues (across different
platforms, NICs, and kernel versions), but have not found anything that
helps with my problem.
I have an API CS20 (dual 833mhz/2GB RAM) with two Intel Pro 100 NICs
integrated. I am happy to report that Lenny successfully installed and
everything I've tried to run on it so far runs great. My intent was to
run this as the firewall+NAT router for my internal network, to take
over for the old PIII 733mhz that is currently filling this role.
Now, my problem, whenever I generate a bit of traffic (it doesn't have
to be much, checking a couple of IMAP accounts will do, as will scp'ing
a few megs either to/from, or across the machine), I start getting a ton
of messages like this for both interfaces:
kernel: [4243778.827184] NETDEV WATCHDOG: eth1: transmit timed out
kernel: [4243778.855504] e100: eth1: e100_watchdog: link up, 100Mbps,
full-duplex
This is sometimes eth0, sometimes eth1, sometimes both back to back. A
good scp session going across this server to a remote (from my network)
machine will cause them both in rapid succession.
ifconfig reports no errors on either interface, I have verified cables
and switch ports are fine (as best I can tell from the switch it's
connected to, it never loses Layer 2 link), all work with other
equipment with no issues. I have tried both the 2.6.26-1-alpha-generic
and 2.6.26-1-alpha-smp (was running smp first) kernels, with no options,
with pci=noacpi and noacpi, same results. I'll be happy to send/attach
any relevant log files/output that anyone may want or need to assist in
troubleshooting this issue. It has been some time since this machine
was booted and used (it was running Sarge prior to install), but I don't
remember any issues before. I'm not a very low-level system driver
person (more of a network geek) but I'd be willing to try pretty much
anything, including giving ssh access to the box to anyone who might
want to assist.
I would appreciate any thoughts either on or off-list as to what I
should do next. I would dearly love to keep this box operating if
possible, but if I can't use the network interfaces, it's pretty much
useless to me at this point. I should also point out that from SRM, I
can assign IP addresses to the interfaces, and pings do not ever lose a
packet either.
Thanks,
Dave
