ACPI / scan: Treat power resources in a special way
In that case, please try to comment out the following two lines:

device_set_wakeup_capable(dev, true);
acpi_pci_sleep_wake(pci_dev, false);

in pci_acpi_setup() in drivers/pci/pci-acpi.c and see if that improves things
for you.
Current git still hangs with those two lines commented out.
What about commenting out the entire contents of pci_acpi_setup(), then?

Still no luck, still hangs at boot.

Also, please send the output of acpidump from the affected machine.

You can find acpidump and dmesg at:

I noticed that booting with serial console enabled succeeds also with failing kernels;
I've to do more testing to see if it's a 100% success ratio.

dmesg is relative to vanilla current git kernel, booted without docking station and with serial
console enabled. Inside it you can find some acpi related error; I don't know if they're relevant.

Kind regards
