cd burning

for some reason, cd burning is awful for me. my cpu usage jumps to 100%, if i'm listening to music it stutters so much that every .75s you hear a .1s burst of music, the mouse becomes jerky and unresponsive, and my system becomes slightly unusable. also, there are constant buffer underruns on the cd burner.

currently i am using the 2.6.7 kernel with the newest k3b and dependancies. k3bsetup shows the drive as an ide drive, which it is.

when i was using fedora core 2, with kernel 2.6.something, ide cd burning was working perfect for me.

can anyone help me out here? it's no fun having an expensive plextor drive when you can't use it...

ephex,

Have you got DMA enabled, both on your burner and HDD?
Use hdparm to find out e.g. hdparm -i /dev/hda

well, i thought it was, seeing how its set up to enable it at boot.
but theres where things get weird. i CAN'T enable dma, wether i use /dev/hda or the really long devfsname. it appears something is not right:

gravity root # hdparm /dev/hda

gravity root # hdparm /dev/hda

/dev/hda:
HDIO_GET_MULTCOUNT failed: Invalid argument
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
HDIO_GETGEO failed: Invalid argument

gravity root # hdparm -d1 /dev/hda

/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
gravity root # hdparm -d1 -X69 /dev/hda

/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
setting xfermode to 69 (UltraDMA mode5)
using_dma = 0 (off)

i think i just realized why... i probably didn't compile in support for my onboard ATA. and i didn't realize it until now because i have a SATA hard drive...

ephex,

If your SATA drive appears as /dev/hdX, you are using the depreciated IDE driver. If you are doing a kerenl build, move over to the SCSI SATA driver,

You will need to fix your /etc/fstab.

You still need IDE DMA configured properly to use it for the writer.
