I'm : wondering if anybody can confirm this or has seen a similar problem with : the Linksys card. It looks like the Linksys card is unable to perform at : 100Mbit/s full-duplex speeds, packets arrive too quickly to be drained : ("ed0: warning - receiver ring buffer overrun"). This is a possible irq problem. I see that you are using irq 7, which the printer port normally uses. If you haven't disabled this device in your BIOS or if the device persists in driving IRQ 7 even when disabled, you must pick another one. To find out for sure, what does vmstat tell you? The other possibility is that the card is one of the newer ones like the fa-410 that needs faselect run.
