Oh, I think I have a small clue... the latter four messages come from
the 8250_pci loading attempt, but the first message is from the 8250 loading
attempt - which also fails (but does the printk which makes it look all
right). A standalone attempt reveals:
% sudo modprobe 8250
FATAL: Error inserting 8250 (/lib/modules/2.6.27-rc4/kernel/drivers/serial/8250.ko): Device or resource busy
%
That should be EBUSY, and that gets mentioned twice in
serial8250_request_std_resource() and once in
serial8250_request_rsa_resource(), after failures of request_mem_region()
and request_region(). Both of those are macros for __request_region().
The stuff past that is uncharted territory for me :)
