I think thats expected. Jeff? > Under 2.4.29 using CONFIG_BLK_DEV_IDE_SATA the DMA is set fine upon > boot, and I get good transfers, hdparm reports 58MB/s on my Western > Digital drive.

If you can't get it to crash without SATA, re-enable it, and get another couple of oopses please. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
