In our experience (we're phasing out the last of 100 or so 3c509s), no. The card itself has a problem with any signifant /output/. In other words, it's a bad card for even a moderately busy web-server, but probably ok for a (perish-the-thought) news box. Under load, the card will simply lose the network, but will recover easily with ifconfig ep0 up. The symptom you are seeing (though not the original poster) sounds like an IRQ conflict. Unless you have set the IRQ in your pnp/pci BIOS config for "Legacy/ISA" you are probably sharing interrupts with a pci video or scsi card. The 3com card will get maybe every 1000th interrupt; I've seen ping times over a /minute/ in this case as the card struggles to get an interrupt. The best strategy if you want to use these old cards in a new machine is to run 3c5x9cfg and manually set the base address and IRQ (typically 300/10), and then assign the IRQ to ISA in your machine's BIOS. With 10/100 Netgear's at $29 it's generally not worth the effort. Brian To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
