realtek 8168/8111 hangs on high load


I'm using a notebook that have a realtek 8168/8111 (r1000) ethernet that hangs during high load (big download and/or big upload). Currently I'm using Kubuntu Dapper. I don't think it's a hardware problem, cause i never had this problem while using windows.

I think that this has something to do with the ethernet not detecting the network speed and duplex correctly. But when I try to control it using 'ethtool', it fails (Dapper's kernel is not recent enough). So I downloaded the module source from realtek's webserver. When I compiled it, I got these errors :

/home/ari197/Downloads/r1000_v1.05/src/r1000_n.c:1295: error: conflicting types for "r1000_tx_action"
/home/ari197/Downloads/r1000_v1.05/src/r1000_n.c:137: error: previous declaration of "r1000_tx_action" was here
/home/ari197/Downloads/r1000_v1.05/src/r1000_n.c:1344: error: conflicting types for "r1000_rx_action"
/home/ari197/Downloads/r1000_v1.05/src/r1000_n.c:136: error: previous declaration of "r1000_rx_action" was here
make[3]: *** [/home/ari197/Downloads/r1000_v1.05/src/r1000_n.o] Error 1

any ideas why it won't compile. Does anybody know any other possibility that might cause the system to crash ??

Thanks before

I suggest to not compile the software from Realtek. It is better to use the one with the kernel. Also the software from Realtek is a lot older than the kernel and probably your compiler is version 4 which is not compatible 3.3. Most Linux modules (drivers) from manufactures mostly compiles for kernel version 2.4.x and with gcc version 3.3.

You are better off trying to do a kernel upgrade, upgrade the BIOS, or check the temperature.

I suggest posting a bug report at

I already tried to use the latest linux kernel (2.6.19), but it still crashes on high loads. Although this time I managed to manualy control the speed and duplex, but to no avail

A bit strange though that on linux-2.6.19, I'm using the r8169 module instead of r1000 module.

Any other ideas are welcome. Now i'm depending on my wireless network for big downloads/uploads, which is
a bit anoying.

I have not have any problems uploading and downloading a file that is larger than a gigabyte using the r8169 module although my NIC is a Realtek 8169 chip on a USB 2.0 and IEEE-1394 combo PCI card from Koutech. Probably it is gcc version 4 is the problem because my kernel is compiled with gcc version 3.4.4 with 4K stack. However, after some time of uploading many files that are 1 GB in size, my ISP froze my connection, so I had to turn off the router for a period of time. It happens on other NIC brands like 3com and Linksys too.

You can try to add a line in /etc/modules.conf to set debugging to all. Add the following to /etc/modules.conf.

options r8169 debug=16

You can try to include use_dac on the same line as above.

Keep an eye on /var/log/messages because it will make some programs stop working from taking 100% of storage space. I suggest using logrotate to help you keep it under control. Next time you re-install or thinking of reorganizing your partition scheme I recommend set /var/log on its own partition, so programs like man and others can work with out being effected by /var/log/messages.
