network interface (marvell gigabit ethernet) stop working after a time

[Peter Chabada]

Up-to-date Dapper installation (2006-Apr-02).

In my testing server I have 2 network interfaces. Intel EtherExpress Pro 100 that I use to connect to internet and is working properly. The second one is Marvell Gigabit Ethernet Controller (88E8053) integrated onboard (motherboard is Asus P5GD1Pro) which I'm using to connect to my home network. I have setup NAT to allow computers in my home network to access internet. I also setup sharing some folders (/var/cache/apt/archives/) on server for computers in home network (samba, nfs, ssh).

Computers from home network can access internet, can browse web, use mail and while this uses small bandwitch (~2 Mbps) everything works fine. They can also download small files from shares. But when they try to download files in total 100+ MiB from shares (in higher speed - 100 Mbps) the Marvell ethernet interface stops working. Computers from network cannot ping this interface (even after restart of these computers) and cannot go through NAT. Server is able to ping this interface but cannot ping computers on home network. After "ifdown eth1; ifup eth1" is everything OK (for a time). Thats why I cannot download big or many files from shares on server and it does not mather if it is samba, nfs or ssh share. While accessing internet from home network through NAT interface broke only once (download of 180 MiB iso image with download manager).

I made a watchdog which is looking if is network accessible and if not it make ifdown and ifup. But this is not solution.

In Breezy worked everything fine.

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this linux-source-2.6.15 kernel bug to the new "linux" package. We appreciate your patience and understanding as we make this transition. Also, if you would be interested in testing the upcoming Intrepid Ibex 8.10 release, it is available at http://www.ubuntu.com/testing . Please let us know your results. Thanks!
