Hi Kevin,

Can you post the output of “scripts/setup.sh status”?

This debug message is not complete and needs to be improved.  It is not enough for ioatdma to not be loaded – those PCI functions need to also be bound to uio_pci_generic or vfio-pci.  The command above will clarify if these functions have been bound correctly.

-Jim

    Hi, all,
    I am using spdk from git on x86_64 platform. I had built it
    successfully, but I am getting
    "Not enough ioat channels found. Check that ioatdma driver is unloaded." error
    after running "/verify" even though "lsmod | grep  ioatdma" shows that
    the ioatdma module is not loaded.  Any idea what can be the reason for this ?
