Use a PCI quirk to unconditionally disable emulated PATA mode, because
it's not needed.

I have disabled the emulated PATA mode this time but the following error is comming in both the ocassion.
When I'm creating the partition using mkpart it is showing "The bus is in an invalid state, Access of this device is not allowed." and ide_open() returns with "No such device".
Please suggest me what could be the problem?
Thanks,
Saumendra
