HDParm settings not staying in place for more than 10 second

bud1979

After i put in dma settings i want my computer hangs for a few seconds and then the settings look like this.

/dev/hda:
multcount = 0 (off)
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 4865/255/63, sectors = 78165360, start = 0

I have the dma enabled in the kernel and in the bios. Any ideas why it would just reset? Thanks

got it now. but how do you get it to work on boot up. I have edited /etc/conf.d/hdparm to what i wannt and added hdparm to default but when it boots it says that it fails applying hdparm to drive0 and drive1. Any thoughts?

You need support for your IDE controller chip compiled in the kernel if you want DMA to work. Use lspci to see what hardware you have :

I had the same problem when compiling IDE chipset support as module and inserting it in modules.autoload. Seems to me as if the startup script executes its hdparm statement before modules.autoload. With linking IDE chipset support static in the kernel, it was ok.
