I was since confused; my disk seemed a lot slower, and it looked like DMA was off. I'm not sure how SATA works; is it even possible to enable/disable 32-bit IO and DMA? Or are those just on? sata_via 11524 4 libata 112660 3 ata_generic,pata_via,sata_via ~$ sudo hdparm -d1 -c1 -u1 /dev/sda /dev/sda: setting 32-bit IO_support flag to 1 HDIO_SET_32BIT failed: Invalid argument setting unmaskirq to 1 (on) HDIO_SET_UNMASKINTR failed: Inappropriate ioctl for device setting using_dma to 1 (on) HDIO_SET_DMA failed: Inappropriate ioctl for device IO_support = 0 (default 16-bit) I no longer have two kernels to test through; I can't tell if the speed is back or not. Nothing in dmesg tells me if SATA is using DMA or 32-bit IO support though, so I don't know... lack of knowledge over here is killing me for troubleshooting this on my own. - -- We will enslave their women, eat their children and rape their cattle! -- Bosc, Evil alien overlord from the fifth dimension -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iQIVAwUBRX7YeAs1xW0HCTEFAQIZ5w/9GCEP1LMCqTAa366wSg6WcwomBL1fsSik xrZJ2ZGAzKyAkKA6DLDKjJ12fG1Pueri5qj7Cx8iRgPOFTnXg3+zNdC26uWJ2cSR hlXI/GkjMAaB2yXidPHkfpsh1fROQoiWPy+wQ8ppXVfW/xwgFUPFst5OWoU/HSbn 8Y72tUDgsj5QjWtn6XendpND8kq59Aqw4A+WG8ThW5FyRNXa5zyd8IW6bSmLGKAa +/PCp937aK6us8LAqlkjqHaqN+JavS+lTxFXb0ZhStKteoGo0z79IvuwnRbNtJR5 XwDBzWhic1IDTV5NOyxDQ0fBoVTllIKeY55v84lzbRrYJOIiKaze1dyDPPT/nAlo 2nS1rXP+X+3RxqUrD5kXorGSHdTqVQoBINfnntrKTkNqAKUNQ4YxlBmwzsoYsIHO /h0hCEFoIp1wFokKEP6/Dz6TM63G3m+tadPLpSbQ2u4yEg8N8vSZeix61EieNoAU nR8YZW52BK6rGc0/IrJRE2fVd90gxSjvN2T3o3Du+cjPHdYQhlvV3GFcIsFVIp3Y GkXO9T29HwgZO/KuA02vhjqgP2WvC5qeV4ansbukGBBi8jaanm6qf7PcsN0/1bNr bWqYCfzvIuIg/FPiK7XzkmVJ6cipBbCHEGqBQiQn6D0lpA715Me+T8uTH3HPUX4l oclOnqemO+w= =TU0m -----END PGP SIGNATURE----- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
