options NET_MPSAFE in the kernel might improve things. I am using it
but it's not considered stable yet. Also you can try to disable ASPM
via fdt; "aspm-no-l0s" property.
How many PCIe lanes does this card have?
Could you send me off-list the output of
"pcictl /dev/pci1 dump -b 1 -d 0"?
Caution: pcictl list is known to trigger a PCI abort and kernel hang on
this SoC, presumably due to a host bridge bug.
