Today I put yet another update of the 3Com Etherlink XL driver at www.freebsd.org/~wpaul/3Com. This version has changes to fix support for 100baseT4 cards and fixes a small bug in the TX error recovery. I'm hoping to commit the 3.0 driver to -current by the end of next week, but I'm still concerned that there may be problems in some configurations. I've have a couple people report problems with performance but lack of followups has made it hard to me to know if these problems are still present. I'm interested mainly in the following: - I have received some reports of spotty transmission performance or 'transmission error' messages. I made a mistake in the code that tries to recover from some of these errors (I wasn't resetting the upload list pointer correctly) which should be fixed now. I'm interested to know if transmission problems persist, particularly with 10Mbps links on slow machines. This applies to all supported cards (3c900, 905 and 905B). - I haven't yet been able to fix the problem with one particular 3c900 COMBO card. This card appears to initialize correctly but refuses to do DMA. The 3c900 card that I have works properly and I haven't been able to remotely debug the problem. If you have a 3c900 card that probes correctly but doesn't appear to transmit and receive, and which does work corretly with the vx driver (which doesn't use DMA), then I'd like to know. Without any other evidence, I'm nearly convinced that this is a hardware problem with this one card. If you have a problem, please let me know. Tell me the type of system you're using, the type of card you have, the version of FreeBSD, and a _DETAILED_ description of the problem, along with a way to reproduce the failure, if at all possible. -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
