That list purposefully has no overlaps > with chipset drivers. The kernel I'm using is 2.6.14. My chipset is Via 82c694x and 82c686b (Abit VP6 dual-P3 with HighPoint 370). DMA is on only when 'via82cxxx' and 'hpt366' are compiled in. Most importantly, DMA cannot be turned on if loading by module. Does it mean that this "bug" is pecular to my chipset? -- William Park , Toronto, Canada ThinFlash: Linux thin-client on USB key (flash) drive http://home.eol.ca/~parkw/thinflash.html BashDiff: Super Bash shell http://freshmeat.net/projects/bashdiff/ - 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/
