Hi Mark, I can see vanilla 3.19.8 has pci_msi_unmask_irq and pci_msi_mask_irq. Also I checked Fedora 3.19.8-100.fc20.x86_64 source code, they are still there. Not sure why getting this error. > Subsequently, the module is may not be loaded on account of same. > (from dmesg): > [673425.712110] igb_uio: Unknown symbol pci_msi_unmask_irq (err 0) > [673425.712124] igb_uio: Unknown symbol pci_msi_mask_irq (err 0) > > Thanks, > Mark
