Huh, not nice. Were those consumer cards or also industrial grade cards? Maybe that is the reason? With the latter, I have never seen this, they always told the truth, so far. Although we mostly used MWDMA, no UDMA to avoid the hardware problems. Regards, Wolfram -- Pengutronix e.K. | Wolfram Sang | Industrial Linux Solutions | http://www.pengutronix.de/ |
