HD in PIO Mode since kernel 2.6.14
Hi,
Since I updated to 2.6.14-1-686, hda is in PIO mode, and when I do
hdparm -d1 /dev/hda i get "HDIO_SET_DMA failed: Operation not permitted".
Im using the default kernel in the debian sid repositories, version
2.6.14-1-686.
It is working fine in 2.6.12-686.
Any ideas?
Thanks in advance.
Ricardo Teixeira.
