Is this really a 3c905 and not a 3c905B? If so, then please try the newest driver at www.freebsd.org/~wpaul. I did find a problem with performance on 10Mbps links. Even if you're not seeing watchdog timeouts, it may be worth a try. > One suspicuous thing: I tried to test this NIC in times of > our network inactivity but we has big number of collisions: > 250, 332, 400 ! It's not good ! The driver adds up single collisions, late collisions and multiple collisions into the one counter. I also see a lot of collisions on my 3c900 on a 10base2 network. -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-hackers" in the body of the message
