Can you report a bug in https://bugzilla.kernel.org so it's easier to
track this?

The problem seems to be that the rootport is not leaving D3 for some
reason when the driver is loaded again.  Do you have
CONFIG_IWLWIFI_PCIE_RTPM enabled in your .config? (you shouldn't)

In any case, better continue tracking this in bugzilla, so please
report it there and include the full dmesg output so we can better
understand what is going on.
