I had some 2.5.28/29 problems (I didn't set the new CONFIG_XXX_SERIAL
options, and it took me a bit to realize the system was really booting
even though I didn't see any serial line output), I hope to post the
patch (against 2.5.29, but it will apply to 2.5.28) by Wednesday.

I have some patches from the multi-path that I could break out, especially
some list iterators - multi-path needs the Scsi_Device separated from
Scsi_Host. Iterators were added so the underlying structures are not
visible - that is, so host_queue is not directly referenced, and I can
put any type of data structure in its place. This is one of the broadest
changes (potentially affects all adapter drivers) in the multi-path patch.
Having Scsi_Device on its own list could also help in hot-replacement
of single pathed devices (Scsi_Host can be removed without having to
remove a Scsi_Device off of its host_queue).
If you make changes in the host/device list(s) please consider that I need
to have the Scsi_Devices on their own list separate from the Scsi_host list.
Thanks.
