On reboot the loop in device_shutdown gets confused by these devices
and goes into an infinite loop. I think this is because they don't
have dev->bus or dev->driver which is because hwif_register_devices
doesn't get called if !hwif->present.

I've been wondering about this a bit and I think that we should just nuke
port from struct ide_host in such situation so I added ide_disable_port()
helper for this (+ fixed ide_register_port() handling while at it).
Could you please re-base your fix on top of attached patch?
Please also remove superflous device_destroy() call -- device_unregister()
should be enough and if it is not we need to fix ide_register_port() to
use unique dev_t instead of MKDEV(0, 0).

This code have to stay unchanged for proper warm-plug support
(luckily after re-basing this chunk shouldn't be needed).
Here is the ide_disable_port() patch:
From: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
Subject: [PATCH] ide: fix ide_register_port() failure handling
* Factor out port freeing from ide_host_free() to ide_free_port().
* Add ide_disable_port() and use it on ide_register_port() failure.

Sure.
Subject: IDE: Disable and unregister devices if initialization fails.
On reboot the loop in device_shutdown gets confused by these partially
initialized devices and goes into an infinite loop. Therefore disable
and unregister these devices.

Hmmm, ide_disable_port() may free hwif so it needs to happen last...
Also did you have a chance to retest this? [ I couldn't reproduce
the issue so was hoping that you could test combined fixes. ]

Oops, new version below.

Yep, I can easily repro. I've actually fixed the underlying issue (a Xen
IRQ problem) causing the probe to fail but can easily revert that fix to
test these patches. If you wanted to repro yourself you could probably
make the request_irq() in init_irq() artificially fail.

I applied the patch (removing leftover hwif->present while at it)
