If they had been buggy and then > fixed I'd have expected much unhappy ranting before the change The "fix" was an hdparm command like hdparm -X66 -m16c1d1 /dev/hda. Which I set for my VIA 686a on a Tyan mobo w a 1G Athlon. Interestingly, initially feeding that chip 40 wire cables (w/o the -X66 of course) would result in the crc errors followed by DMA turn off, about 85% of time... Other 15% was fine and DMA worked great. I then switched to the 80 wire cable and DMA became rock solid at which point the -X66 was added. Just thought I'd add some data points :) > > - > To unsubscribe from this list: send the line "unsubscribe linux-kernel" in > the body of a message to majordomo@vger.kernel.org > Please read the FAQ at http://www.tux.org/lkml/ > ----------------------------------------------------------------- John Heil South Coast Software Custom systems software for UNIX and IBM MVS mainframes 1-714-774-6952 kerndev@sc-software.com johnhscs@sc-software.com http://www.sc-software.com ----------------------------------------------------------------- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
