Comment (by tkn...):
There are some other tickets which may be related to Lantiq Danube PCI
problems causing USB or Wifi problems:
#18369 new defect
CC r43224 / ARV752DPW22 / 2 of 3 USB ports doesn't work
#19856
Lantiq ARV752DPW wifi broken
On my Easybox 802/ARV752DPW with CC the bootlog showed (and wifi does not
work thereafter):

Would be great for the others, if this could be fixed in trunk.
I can not test it, because the Easybox is in active use now with BB (PCI
works there for me).
May be some code now checks IO_SPACE_LIMIT. The "#define "IO_SPACE_LIMIT
0xffff" is the same in BB, kernel version 3.10.49.
