Thread-topic: BUG: unable to handle kernel paging request

Hi, When trying to bind VF to igb_uio on a PV machine I get the following error the module crashes BUG: unable to handle kernel paging request Xen dmesg shows mm.c:618:d1 Could not get page ref for pfn df300 I'm new to dpdk so if you need any other information let me know.
