Now this is odd! I think I may have found something! > > All of my 'rl' driver cards fail this test: Oh sure. Bet the farm on the absolute worst NIC on the whole damn planet, why don't you. Why spend a few bucks on some nice 3c905B or 3c905C cards and beat up on them when you can buy ten RealTek cards for a dollar. About as reliable as a pair of tin cans and a piece of string, but gosh they sure are cheap. You'll have to wait until at least tomorrow before I can look into this, since I won't be able to do any debugging until I throw my one and only RealTek 8139 sample adapter into a machine and run some tests with it. > rl0: irq 11 at device 3.0 on pci0 > rl0: Ethernet address: 00:50:ba:d1:89:05 > miibus0: on rl0 pciconf -l would be nice here too (to see the PCI revision code). > Methinks there is something going on with the 'rl' driver and/or > the RealTek cards! Gee, y'think? I don't suppose you ran any similar tests with, say, one of those LinkSys cards you had the other day. Or maybe a 3Com card. I mean, it's just a little anti-climactic, you know? I put all that blood, sweat and tears into if_xl and if_dc, but do people do stress tests with them to help me identify weaknesses? No, they pound on the house of cards that is if_rl. *sigh* -Bill -- ============================================================================= -Bill Paul (212) 854-6020 | System Manager, Master of Unix-Fu Work: wpaul@ctr.columbia.edu | Center for Telecommunications Research Home: wpaul@skynet.ctr.columbia.edu | Columbia University, New York City ============================================================================= "It is not I who am crazy; it is I who am mad!" - Ren Hoek, "Space Madness" ============================================================================= To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
