Hi,

Recent patch 399a3f0d (igb_uio: fix IRQ mode handling) has introduces new IRQ mode handling code.

As Stephen reported earlier, VMware PCI emulation of interrupts is somehow broken, so INTX mode is not supported (see http://dpdk.org/ml/archives/dev/2014-May/002432.html). The current code makes VMware e1000 unbindable to igb_uio driver and throwing -EIO error.

What I suggest is to throw a kernel warning but make the work with this kind of NIC possible.
