Description Willem Riede 2004-02-28 14:07:03 UTC 
Description of problem:
The ide-scsi module is not compiled and distributed which makes it
hard to use tape drives that do not work (properly) with ide-tape,
such as the OnStream DI-30, with Fedora Core going forward.

Version-Release number of selected component (if applicable):
2.6.3-1.*

How reproducible:
modprobe ide-scsi fails

Steps to Reproduce:
1. install fedora core test (1.90)
2. as root, run "modprobe ide-scsi"
3.
  
Actual results:
FATAL: Module ide_scsi not found.

Expected results:
quiet success

Additional info:
As I wrote in
http://marc.theaimsgroup.com/?l=linux-kernel&m=107246268217888&w=2 I
need ide-scsi to survive. Why? I maintain osst, a driver for OnStream
tape drives, which need special handling. These drives exist in SCSI,
ATAPI, USB and IEEE1394 versions.

One high-level driver, osst, handles all of them, and that's how it
should be, right? For ATAPI, it relies on ide-scsi.

(Yes, ide-tape contained code for the ATAPI version, the DI-30, but
that code is old and has serveral known problems - and has been removed).

But, you object, ide-scsi is buggy. Well, I claim to have fixed that,
the patch is in -mm. But, you object, I don't want cd-recorders to use
ide-scsi. Well, I submitted a patch that makes ide-scsi only attach to
drives it is told to attach to, and not grab ATAPI drives by default:
http://marc.theaimsgroup.com/?l=linux-kernel&m=107628037518550&w=2

So, can we please include ide-scsi.ko in the next test release? At
least to see if it behaves better now?

Patch to make ide-scsi attach more selective

With this patch, ide-scsi will _only_ attach to drives that are specified with
the hdX=ide-scsi parameter to the ide subsystem.

118406 is a dupe.

Patch to fix ide-scsi error handling, also in -mm

Attached patch to fix ide-scsi error handling obsolete as of 2.6.5-rc2 since
Linus has incorporated an improved version of this patch in the mainstream
kernel. This should remove any lingering concerns about re-enabling the
ide-scsi module in future kernel builds.

- 2.6.5-mc4
- reenable sg driver for scsi tape changers and such

I am not sure if this is related, but does the 326 kernel help the
situation at all?
Comment 6 Willem Riede 2004-04-20 14:53:05 UTC 
No, the 326 kernel does not help, since the ide-scsi module is still
not compiled:

[root@fallguy root]# grep BLK_DEV_IDESCSI

/usr/src/linux-2.6.5-1.326/configs/kernel-2.6.5-i586.config:#

Comment 7 Dave Jones 2005-02-24 06:07:18 UTC 
should be fixed these days ? confirm ?
Comment 8 Willem Riede 2005-02-26 14:29:20 UTC 
yes it is - has been fixed for some time. please feel free to close this bug.
