DAO doesn't work with the stock scsi drivers (at least not through
2.4.18). You need to apply a patch to the kernel drivers to get
it working otherwise use tao.

Do you know where I could find this patch (or who wrote it?)

I got it off of this list myself, I think it was originally for
2.4.3. I've just kept remaking it as I put new kernels on
my machine as it seems to never have made it to the official
kernel. It patches several scsi drivers but the only ones that
affect Mac users are  the 53c94 and mesh drivers.

http://www.jriver.com/~bob/daofix-2.4.17.diff

Is against the 2.4.17 kernel. I just tried it on the latest
benh 2.4 kernel (2.4.20-pre7) and it patched ALTHOUGH there
were offsets in the mesh driver which seems to have been worked
on lately. I haven't verified that it works past the 2.4.19
kernel I'm currently using. YMMV.

Interesting. I don't think this patch does things the right
way though, but I'll see what I can do with it.

If I remember right the author of the patch was trying to reduce
the redundancy of the same code in several scsi drivers and do
a more generic setting of the scsi direction flag. This is a pretty
common problem, I've seen the same limitation in the Adaptec 3200
driver as well as in other OS. It would be great if some kind
of fix got into the main tree, THANKS!!

/proc file system not working

[Sanjeev Manral]

Hi all,

We are developing linux on powerPC405 and trying to enable /proc file
system.
/proc/ioports and /proc/iomem contains nothing.
What could be the reason?

cdrecord, cdrdao failing with scsi bus reset

[Tony Howard]

List,

I am having a problem with my cd recorder, and I was hoping someone could
help.  I have copied an audio CD to my HD using cdda2wav, but trying to
write with cdrecord causes a SCSI bus reset.  cdrdao fails with a different message,
but I get an identical scsi bus reset according to the kernel logs.  After
the reset, I can't access the CD drive until I reboot.  Relevant info:

Apple Performa 6400

Linux 2.4.20-pre5
cdrecord 1.10
cdrdao 1.1.6
Drive: Sanyo CRD-R880S, aka Smart & Friendly CD Rocket 8020

Here is what's on my scsi bus:

I get the following lines in my kernel log:

Does anybody have any suggestions?  I don't think its termination issues -
I just have the built in CD and the external burner, and it has a
termination switch which is set to on.
