Given that sata_nv uses devres like other libata > drivers, IMO the likely cause is outside the ATA subsystem (PCI? ACPI?). I will follow up on this with the appropriate subsystem lists ASAP.

I am not quite sure what to do about this part... my boot device for the system is on one of the sata_nv channels which remains functional and does not get disabled by the resource conflict. How shall I best attempt the suggested workaround without having to delete the sata_nv driver from the kernel thus rendering the kernel unbootable on this machine? Is there some way to pass the appropriate option at boot instead of at module load time or some file I could modify to enable the specified option in the code? > Jeff Thanks for the fast reply!
