[Qemu-devel] ide_generic: please use "probe_mask=0x3f" module parameter for probing all legacy ISA IDE ports

[Atlas Khan]

I am running a VM and giving it a qcow file as its root file system.
But it is giving me following error.

ide_generic: please use "probe_mask=0x3f" module parameter for probing
all legacy ISA IDE ports

Can any one tell me what is the kernel configuration to solve this error.

if you want full output of my system then it is as follow
