I am seeing this in my kernel log:
[ 10.235625] tg3 0000:03:00.0 eth20: No interrupt was generated using MSI.
Switching to INTx mode. Please report this failure to the PCI
maintainer and include system chipset information
I looked through MAINTAINERS, but I can't find the PCI maintainer.
Can anyone help?
Chipset info: this happens on a Freescale i.MX6Q. Mainline 4.19 kernel.
The devicetree entry for the pcie chipset is here:
arch/arm/boot/dts/imx6qdl.dtsi:
pcie: pcie@1ffc000 {
compatible = "fsl,imx6q-pcie", "snps,dw-pcie";
<snip>
};

It sounds like you might be hitting the bug I posted a fix for
recently.
