No DMA with kernel 2.4.27-1-686
Package: kernel-image-2.4.27-1-686
Version. 2.4.27-1-686
After updating the kernel to the newest version, two different machines wont run with DMA access.
The first system is an IBM R50 Notebook, the other system is an Gigabyte BX2000 Mainboard with a Intel BX Chipset.
With all the older Versions (<=2.4.26-4-686) it worked fine!
When I try to activate the DMA via hdparm:
pluto:~# hdparm -c1 -d1 /dev/hda
/dev/hda:
setting 32-bit IO_support flag to 1
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
IO_support = 1 (32-bit)
using_dma = 0 (off)
The Kernel Messages with the older 2.4.26:

Now with 2.4.27:

Aug 17 17:24:01 pluto kernel: ide: late registration of driver.

Aug 17 17:24:01 pluto kernel: ide1 at 0x170-0x177,0x376 on irq 15
Aug 17 17:24:01 pluto kernel: Journalled Block Device driver loaded
Aug 17 17:24:01 pluto kernel: hda: attached ide-disk driver.
Any ideas what's wrong?
Thank you
