SCSI DVD Drive Errors

Hi

I recently moved from 2.6.12-gentoo-r7 to 2.6.14-gentoo-r6. At the same time I got automounting working with pmount/dbus and emerged KDE 3.5.

In the confusion of getting used to pmount etc I found that my Pioneer SCSI DVD Drive seemed to have developed a fault which I initially put down to the new automounting enviroment. After spending most of an afternoon trying to find the fault and almost giving up on the drive as dead I thought about booting back into 2.6.12. It worked, the seemingly dead drive sprang back into life and works as happily as before.

So, what's changed SCSI wise 2.6.12 --> 2.6.14?

Here's what dmesg shows for both kernels:-

I have 2.6.14-r2 and everything works with aic7xxx. (I have DVD and CDR). Could it be some termination or cabling problem? Could you post output of cat /proc/scsi/aic7xxx/0 please?

OK. My (very wild) guess is: some setting with newer kernel is a little more agressive and this is why your misconfigured(?) h/w fails to follow. Termination thing. You should not use terminator on controller side, controller terminates it's end automatically. Active terminators require external power. If your DVD has no jumper marked TPwr or something like this and this is not activated then with current setup the device side is probably not terminated.
My advice. Remove both external terminators. Enable internal terminator in DVD-ROM. Connect one end of cable to controller and the other end to the DVD. Do not use sockets in the middle. Open ends cause serious problems. Cut your cable shorter if necessary.

Thanks for your comments. I tried all sorts yesterday after reading your reply, removing terminators, shortening the cable, changing IDs, swapping chains and all gave the same result. A duff drive under 2.6.14 and a working one under 2.6.12.

Ah well, I'll persevere. It won't defeat me! :evil:

Sorry to hear it.

One last thing. Go into SCSI BIOS and reduce transfer rate for this device. (Ctrl+A from startup screen)

Hi,

had the same problem: http://bugzilla.kernel.org/show_bug.cgi?id=5659

Using linux-2.6.13-gentoo-r5 + dbus/hald works without problems.

I stress-tested the drive, it also works on other OS as well, such
as latest Kanotix 2005-04/kernel 2.6.14.5.

Using vanilla-2.6.15/gentoo-2.6.14_all_versions + dbus/hald
produces the logged errors and renders the drive practically unusable.
Turning of dbus/hald solves the problem.

Yep - same here. Simply stopping hald here brings the drive back to life (still 2.6.14-gentoo-r6). Going to build 2.6.15(gentoo) this weekend to see what happens.

Hi,

I just reopened this bug @ bugzilla.kernel.org as I neither have dbus nor hal installed and I still suffer from this error when starting k3b or kscd with any kernel higher than 2.6.13.x.

Cheers

Hello

I encounter the almost same error with my rig.

The SCSI burner ID3 lead to error similar to this :
Nov 25 21:07:15 gentoo (scsi0:A:4:0): No or incomplete CDB sent to device.
Nov 25 21:07:15 gentoo scsi0: Issued Channel A Bus Reset. 1 SCBs aborted
Nov 25 21:07:15 gentoo sr 0:0:4:0: SCSI error: return code = 0x10000

Just the return code is = 0x70000

So, I just wanted to bump this topic to know if anyone managed to get rid of this problem

Hi,

just some URLs where the same problem was reported:

http://bugs.kde.org/show_bug.cgi?id=117693
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=340045
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=339871
http://bugzilla.kernel.org/show_bug.cgi?id=5776

I hope this will get fixed soon. I don't want to stay with linux-2.6.13.x forever

Cheers

Same problem with Gentoo-sources-2.6.16
Has anyone found a solution for this????

hamletmun

Well... after git bisecting... I found this.
It has been a painful process: rebooting from 1966 revisions to 1 revision.
That means 1966->983->492->....->8->4->2->1 and, at least, two rebooting between
the numbers

Now someone has to find the solution for this problem

[SCSI] correct transport class abstraction to work outside SCSI

I recently tried to construct a totally generic transport class and
found there were certain features missing from the current abstract
transport class. Most notable is that you have to hang the data on the
class_device but most of the API is framed in terms of the generic
device, not the class_device.

These changes are two fold

- Provide the class_device to all of the setup and configure APIs
- Provide and extra API to take the device and the attribute class and
return the corresponding class_device

I could be wrong, but gentoo-sources-2.6.17 with up-to-date ~x86 stuff does not have this problem anymore. I did not try to reproduce this bug for weeks so I do not know what really fixed it.
