We have been developing an application that communicates with I2C/SMBUS devices where the comms includes multibyte read and write. When we run on a standard 2.6.18 kernel we have no issues, but as soon as we move the application to dom0 of a Xen kernel based on 2.6.18 , we are unable to do multibyte read and writes. It appears in the debugger either the ioctl interface or the driver no longer works correctly. The h/w we are using is ICH7 and a Intel Core 2 Duo with VT. Does anyone know how Xen impacts the I2C drivers if at all or the PCI interface to the chipset (I assume that it is not behaving correctly when we communicate to the chipset).
