Help text

Use PCI MSI (Message Signaled Interrupts) per default. Enabling this might lead to I2C errors originating from the bridge in conjunction with certain SATA controllers, requiring a reload of the ddbridge module. MSI can still be disabled by passing msi=0 as option, as this will just change the msi option default value.

If you're unsure, concerned about stability and don't want to pass module options in case of troubles, say N.
