The problem in dpt_i2o could be the pci config space accesses it
triggers as it loads, dangerous to do if there is any I/O activity going
on in the other driver (probable if a boot driver I guess).

I approve this patch to dpt_i2o.c, and am applying it to the Adaptec
branch of the driver.

Thanks for the investigation Ryoji.

In linux 2.6.15, data transfer does hang when both dpt_i2o
and i2o_block drivers are loaded.
It seems that location of pci_request_regions() are wrong.
I moved it just behind pci_enable_device() like other drivers,
and it becomes fine.

Miquel van Smoorenburg <miquels@cistron.nl> forwarded me this fix to
resolve a deadlock condition that occurs due to the API change in
2.6.13+ kernels dropping the host locking when entering the error
handling.  They all end up calling adpt_i2o_post_wait(), which if you
call it unlocked, might return with host_lock locked anyway and that
causes a deadlock.

Prevent driver from loading if another driver (i2o) has already claimed
the resources associated with the card. Discussion associated with this
bug can be referenced at http://bugzilla.kernel.org/show_bug.cgi?id=4940
where it was agreed to use pci_request_regions in both the dpt_i2o and
the i2o driver to prevent both drivers loading on the same adapter(s).

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
