The IMX6 PCIe host controller does not fire legacy interrupts if MSI is enabled. A patch is being worked on to enable MSI at runtime only when it is needed but meanwhile this patch will disable MSI for the imx6 kernel. This fixes the no interrupt issue on cards/drivers that use legacy interrupts such as ath9k.

enabled. A patch is being worked on upstream to only enable MSI at runtime

when needed, but until that is ready we will allow MSI to be disabled.
