We were able to resolve this by enabling MSI interrupts in our PCIe core and our Linux device driver.
Thanks go to Scott Duplichan for his helpful guidance.

We are testing coreboot with our new IMB-A180 based AGESA design, and DMA interrupts are not functioning. I am looking into the Coreboot Options, but is there a recipie for enabling legacy interrupts in AGESA? We configure in Linux at IRQ 17.
Thanks in advance,
