Hint: a standard PCI 32bit/33MHz PCI bus can transfer 132MB/s, which is slightly greater than the throughput of a single GigE NIC which is a little over 100MB/s. If the NIC is the only device on that bus, then you have no worries, and likewise if the bus is shared with a low bandwidth PCI device or two. What motherboard is this again and which RAID card? Apologies if you already posted it and I missed it. -- Stan -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe". Trouble?

I had to down load the realtek and compile it. I was experiencing weird issues with my NIC aswell, check if you have the r8169 kernel module loaded, if so, that might be the cause of your crashes. Get the proper drivers for your NIC on the realtek website, compile them against your kernel, run depmod, blacklist the old module, update initramfs and you shouldn't have any more trouble. -- Davide Mirtillo -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

From: Nathen on 6 Jul 2010 14:20 I posted this earlier but it's not appeared on the list for some reason: Sorry about the delay I didn't have a chance to try anything yesterday. Anyway I've just tried a direct connection, updating BIOS, compiling and installing the latest drivers and it's still the same, if not worse - it seems I can crash it with as little as two iperf runs now. I'm still relatively inexperienced with Linux though so I might be doing something wrong. I haven't managed to find that PCI card yet but I'll keep looking or try to borrow one from a friend or something. I'm using an Intel Atom D510MO board and no RAID. -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe". Trouble?

I've had such great luck with them and the cost is low enough there's no legitimate reason to even try competing products. These cards simply work, and work well. Totally compatible, totally reliable. Did I mention they're fast? They push wire speed all day long if the rest of the system is up to the task. -- Stan -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe". Trouble?
