Cannot enable DMA for my IDE-disk [solved]

[paddlaren]

Hi!

I cannot enable DMA for my IDE-disk on feisty. This occurs on both my installations.

Offcorse I do this as root.

#hdparm /dev/hda
/dev/hda:
 multcount  = 16 (on)
 IO_support = 0 (default 16-bit)
 unmaskirq  = 0 (off)
 using_dma  = 0 (off)
 keepsettings = 0 (off)
 readonly  = 0 (off)
 readahead  = 256 (on)
 geometry  = 16383/255/63, sectors = 39070080, start = 0

#hdparm -q -m16 -q -W0 -q -d1 /dev/hda
 HDIO_SET_DMA failed: Operation not permitted

Anyone got a clue?

Yeah, this is because of a change to libata: http://ubuntuforums.org/showthread.p...b048a&t=324373

Re: Cannot enable DMA for my IDE-disk

Well, I followed the hints in the posts and in the bug-ticket and it didn't work out. I do already have the herd 1 installed (i installed from the CD), I unpacked the inird and all drivers the is included in the kernel for ata and ide is also present in the initrd.

The sdparam just complains and would do nothing.

Any more hints?
Can I run on a kernel from my 6.10 installation? Is there more than the /lib/modules/<right version>/ to copy (and the stuff in /boot)?

The kernel was updated together with the initrd which seemed to solve the problem.
