I installed lvm on my new machine which is IBM thinkpad R40. DMA is set
up, as from hdparm /dev/hda the output is :
/dev/hda:
multcount = 16 (on)
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 5168/240/63, sectors = 78140160, start = 0
but when I copy a large file which is about 700m from one place to
another, it costs me 120s, I don't know what's wrong with the dma.
Any ideas?
