Hi,
I recall someone else had discussed this a while ago, but with no answers
from the developers.
I have an Aladdin V chipset and the 2nd IDE channel is only detected if
I insert
options DISABLE_PCI_IDE
in my kernel config file. This option is nowhere documented but only with
this option enabled my secondary IDE channel and its CDROM drive is detected
properly. I didn't notice any performance degradation on the 1st IDE channel.
(I get 11 MB/s with only 5% CPU usage)
What does this option do exactly? Could it be somewhere documented (at least
in options.i386, so I don't get the warning message from config?) Or is there
a better workaround on the way form Aladdin V chips?
Perhaps the problem arises because only the 1st IDE channel is DMA capable?
Daniel
Here is my dmesg output, if it helps (with DISABLE_PCI_IDE)
