It turned out that the card works well in the HP Brio but not in my own machine. I tracked it down to the fact that HP Brio BIOS has option to set bus-master for PCI slots excplicitly whilst my machine BIOS don't. I have Chaintech CT-6ESA2 board with Award BIOS, don't know which board the HP has, but it has Phoenix BIOS. Both motherboards have same chipset, 440LX. I've disabled the bus-master for PCI slots in the HP BIOS and the card behaves similarly as in my machine after that. General symptoms are that link is up, but no packets go over it, sometimes I can get icmp responses with around 10000ms times, but only two-three responses. I get messages "tx0: can't stop Rx DMA" repeatedly. Usually the icmp responses appear suddenly after setting the interface to promiscuous mode (using tcpdump). Two-three responses, then silence. Drop the promiscuous mode and again two-three icmp responses, then silence. All that means that I have ping going on all the time. I remember that some time ago there was something with fxp driver not setting up bus-master bit programatically, but needs machine BIOS to do that. Can it be same? Otherwise the card works. I had 8-hours of netperf running on the both sides over 100Mbit full-duplex connection (D-link switch). On the other side was EtherExpress 100+ card. Certainly this is nothing near to usual workload. The card itself has chipset 83C171A2QF P, not 83C170. Newer, better? Until now, I haven't had any problems with this card in the HP Brio machine. -- Vallo Kallaste vallo@matti.ee To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
