Kernel 2.4.21 causes hangs and/or ooops during boot up if I have a
"probeall scsi_hostadapter ide-scsi" in my /etc/modules.conf. If I take
out that line and manually load the module after the laptop has booted,
everything is fine.
There were no such problems in 2.4.20 or earlier kernels.
Please cc me any responses as I am not on the mailing list.

I probably have the same CD-RW that you do (in the T30) and
I just use hdc=ide-scsi on kernel command line, no need for
manually loading. Works fine but don't try burning with
magicdev running :)
Do you have ide-scsi built as a module though?
I use hdc=ide-scsi (or hdc=scsi) as a boot parameter too. But the
difference seems to be whether you have ide-scsi built as a module or
into the kernel. The reason I think I chose to have it as a module all
these years (on previous thinkpads as well) was so I could remove the
module and swap the dvd/cd-rw for another device.
I haven't had a problem with this configuration(hdc=ide-scsi and loading
the module through modules.conf) with any of the previous stable
releases of the kernel (pre 2.4.21.)

Yes. It works fine, I just tried with cdrdao using
generic-mmc driver. I have nothing at all in modules.conf
related to cd, ide, or scsi.
whoops forgot to add you to CC list as per your request

I think you are saying that its not a module. Here is another report of
a similar problem to mine:
http://www.music.columbia.edu/pipermail/linux-audio-user/2003-June/005119.html
He eventually solved the problem by making sure the ssci support wasnt
built as modules. (Follow the thread above).
There definitely seems to be a problem. If its not a problem but rather
a feature then I would like to know more about why we need to compile it
into the kernel...(i.e. what do we gain )..

it just doesn't get any clearer than that.
