2.4.20-pre5-ac1: IDE DMA problem with Intel D845GVB, resource collisions

["Micskó Gábor" <trey@debian.szintezis.hu>]

Hi!

I have a DMA problem with Intel D845GVB chipset. I use the latest BIOS
for this mainboard (29.08.2002). I try with 2.4.20-pre5-ac1,
2.4.20-pre4, but does not work. 

#hdparm -c 1 -d1 -m16 -X69 -k 1 /dev/hda

/dev/hda:
 setting 32-bit I/O support flag to 1
 setting multcount to 16
 setting using_dma to 1 (on)
 HDIO_SET_DMA failed: Operation not permitted
 setting keep_settings to 1 (on)
 setting xfermode to 69 (UltraDMA mode5)
 multcount    = 16 (on)
 I/O support  =  1 (32-bit)
 using_dma    =  0 (off)
 keepsettings =  1 (on)

(2.4.20-pre4)

Any idea?
