NETDEV WATCHDOG: eth0: transmit timed out



Hi there!

I'm having issues with my eth card - it just stops working. There is
nothing you can do to restore it. The only solution is to restart the
machine, and I've tried a couple of things like rmmod (and then insmod)
with the network module and nothing, the only thing is to reboot.

I'm having this problem w/ my fc5 box (2.6.17-1.2187_FC5 /
vmlinuz-2.6.18-1.2257.fc5). It's an Asus notebook network card - here
are some infos:

02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL-8139/8139C/8139C+ (rev 10).

When it crashes dmesg just dumps
NETDEV WATCHDOG: eth0: transmit timed out
eth0: Transmit timeout, status 0c 0005 c07f media 50.
eth0: Tx queue start entry 4 dirty entry 0.
eth0: Tx descriptor 0 is 0008a062. (queue head)
eth0: Tx descriptor 1 is 0008a062.
eth0: Tx descriptor 2 is 0008a597.
eth0: Tx descriptor 3 is 0008a062.
eth0: link up, 100Mbps, full-duplex, lpa 0x45E1

There's a word going that it might be solved by doing
ethtool -K eth0 tso off
Well in my case it's not supported or some kinda because I'm getting
those msgs:
Cannot set device tcp segmentation offload settings: Operation not
supported

As I've googled in the last month, i've found out that there might be
an irq conflict - I've done some playing around this and i'm not shore
that that could be the problem, more likely there's a problem with the
2.6 kernel and my driver and my lan card.

Here's my current lsmod section that might help:
mii 5825 2 8139cp,8139too
8139too 27201 0
8139cp 24513 0

You cannot understand where it's actually gonna go down, at list i'm
not able to. Usually while i'm downloading with a greater speed then
~500KBps. That's one of the reasons i've configured traffic control
(TC) on my computer, so it'll never go beyond that speed..

I've read something about sky2, but i'm not familiar with that, can you
ppl help me out with this one please?

Many thanks,
BC
