The alim15x3 module in kernels 2.6.3 and 2.6.4 does not allow me to turn
on DMA via hdparm:
hdparm -d1 /dev/hda
HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off)
dmesg |grep -i ali
ALI15X3: IDE controller at PCI slot 0000:00:0f.0

ALI15X3: port 0x0170 already claimed by ide1

---
In kernel 2.6.1 it worked OK:
hdparm -d1 /dev/hda
/dev/hda:
setting using_dma to 1 (on)
using_dma = 1 (on)
dmesg |grep -i ali

These are errors - ide0 and ide1 are already used by generic IDE driver.
It was fixed in 2.6.2 but side-effect of the fix is that you must make sure
that ide_generic driver is not compiled in or loaded if it's modular.
Please make sure CONFIG_IDE_GENERIC is 'n' in your .config.

That worked, I am happily using DMA with alim15x3 on 2.6.4 now. Thank
you for your help.
