Bug is also reproduceable with kernel 2.6.15-rc6

Tested Kanotix 2005-04 with kernel 2.6.14.5, which has many patches.
There this bug does not occur. So either Kanotix has some patches which
solve the bug or the bug is Gentoo-only. I will try to investigate further.

This happens with vanilla 2.6.15 on Gentoo:

Jan  5 02:34:34 gentoo (scsi0:A:4:0): No or incomplete CDB sent to device.
Jan  5 02:34:34 gentoo scsi0: Issued Channel A Bus Reset. 1 SCBs aborted
Jan  5 02:34:34 gentoo sr 0:0:4:0: SCSI error: return code = 0x10000

Stopping dbus and hald solves the problem.

Hi,

I neither have hald nor dbus even installed on my system and I still suffer from
this error so please reopen the bug. I cannot upgrade to any kernel higher than
2.6.13.x because of this bug. More worse sometimes the resets of the scsi-bus
come so frequently that the entire system freezes and I have to hard reset the
machine.

Lars

Still happening for me with 2.6.16-rc1

Seems to me that Lars and spiralvoice have different problems.

For the record, with dbus+hald enabled the bug still occurs with vanilla 2.6.16-rc1

Deactivated dbus+hald, copying files from DVD works without problems,
as already stated, but starting k3b in this situation produces lots of
error messages in logfile, the same Lars had:

Seems to block packet writing as well. 

Same problem here : http://bugzilla.kernel.org/show_bug.cgi?id=5921

Bug is still present in 2.6.16

Bug seems to be still present in 2.6.16.1
Tested with gentoo-sources-2.6.16-r1
http://dev.gentoo.org/~dsd/genpatches/

Same problem with

mm-sources-2.6.17_rc1-r1
vanilla-2.6.17_rc1

More and more I get the impression that nobody is interested in fixing this
problem :-(

I think the severity of this bug should be raised... :-)   
The old kernels we're using are becoming more and more collections of bugs and  
security holes themselves, as time passes and newer versions emerge rapidly.  
  
Mike Anderson, can we assist in any way finding the cause of this bug? :-)  
:-)  :-)  :-)  

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

Author: James Bottomley <James.Bottomley@steeleye.com>                          
Date:   Sun Aug 14 17:09:01 2005 -0500                                          

    [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

After git bisecting... I found this
http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff_plain;h=d0a7e574007fd547d72ec693bfa35778623d0738;hp=10c1b88987d618f4f89c10e11e574c76de73b5e7

could be causing the problem.

To verify the result, I applied this patch to vanilla 2.6.13
At least it boots, but this is the output I obtained:

Just out of curiosity...

Is this bug affecting every devices that use aic7xxx module
or just Adaptec 29160 Ultra 160 SCSI Controller???

I tried linux-2.6.13 with patch-2.6.13.4.bz2
It works fine

and sorry for double posting...

Reply-To: ishikawa@yk.rim.or.jp

Hi,

Just for comparison purposes, I have an Adaptec 29160 in my PC and
it runs just fine under 2.6.15.

To wit,

I suspect that there may be some configuration issues. I mean maybe some
configuration differences might explain why your box sees the problem while mine
doesn't.

I notice that I don't have libata, for example, since I  have no
sata disks in my two/three years old PC.

It might be wise to forget about 2.6.14 and try the latest 2.6.15.x series.

I tried 2.6.14-2.6.17_rc1, vanilla & mm kernels, gentoo-patched kernels...
Already compiled like 50 times, I think, including "git bisect"

But Your post made me think for a while...

Can you tell me the BIOS version number?
I have Latest BIOS of Adaptec 29160 - 30 May 2001
http://download.adaptec.com/eprom_bios/29160_bios_3100.exe

Do you have only one device in the controller?
Maybe I should try without sata & cd drives...

Hamlet, I use an older card that is effected by this bug (check links some 
lines up). 
AHA-2904/Integrated AIC-7850 (rev 03)

        aic7850: Single Channel A, SCSI Id=7, 3/253 SCBs 
 
Could it be a compiler issue?

The card and driver definitely work.  I also have one in my scsi test
rig.  The problem here seems to be a bad interaction with a DVD writer.
The only real difference between this and a standard SCSI disk (as far
as the driver sees it) is the untagged queuing, which is why I suggested
that first.

Same problem with 2.6.17_rc2

I disconnected all the devices (CDROM,CDRW,ZIP) except the disk (Western
Digital Ultra160)
And the kernel 2.6.17_rc2 showed the same screen... CRC Mismatch, Recovery ...
Maybe the problem is not "untagged queuing" as James said.

Same error with 2.6.17-rc1-mm3

http://lists.debian.org/debian-kernel/2005/12/msg00290.html

I symlinked the driver dir to an older working aic7xxx driver, and recompiled a 
2.6.15 kernel...  
 
# ln 
-s /usr/src/linux-2.6.12-gentoo-r6/drivers/scsi/aic7xxx /usr/src/linux-2.6.15-gentoo-r8/drivers/scsi/aic7xxx 
 
The problem remains the same. The cause of the bug must be outside the driver's 
code. 

Created attachment 8157 [details]
serial console info of aic7xxx error with 2.6.17-rc4

Finally I could buy the cable and do some soldering.

It still shows the same error:

aic7xxx_abort returns 0x2002
 0:0:0:0: Attempting to queue a TARGET RESET message
CDB: 0x3b 0xa 0x0 0x0 0x0 0x0 0x0 0x0 0xff 0x0
aic7xxx_dev_reset returns 0x2003
Recovery SCB completes
...............

But this kernel is, at least, able to boot and login.

Same as the above but without 50-pins

Today I did some tests

linux-2.6.14-rc3 and linux-2.6.14-rc1 had the same error, but linux-2.6.13.5 was
fine.
So I guess this bug was introduced between 2.6.13.5 and 2.6.14-rc1

http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=shortlog;h=v2.6.14-rc1

2.6.17-rc6 still shows the same error messages

Using latest kernel 2.6.17 on most up-to-date Gentoo ~x86 I could not reproduce
the bug anymore.

For me, 2.6.17 still shows the same messages.
I will try 2.6.17.1 soon.

2.6.17.3 doesn't work either

kernels between 2.6.14-rc1 and 2.6.17.3 don't work with my Adaptec 29160 SCSI
host adapter

@hamlet:
Here the bug is really fixed, I am using Gentoo ~x86,
please check the versions of these packages:

# emerge -pv hal dbus gentoo-sources

[ebuild   R   ] sys-apps/hal-0.5.7-r3  USE="acpi -crypt -debug -dmi -doc
-pcmcia" 1,492 kB
[ebuild   R   ] sys-apps/dbus-0.62  USE="X gtk qt3 -debug -doc -mono -python
-qt4" 1,696 kB
[ebuild   R   ] sys-kernel/gentoo-sources-2.6.17-r1  USE="-build -doc -symlink" 0 kB

I do not know what has fixed this bug, but its away now.

I tried vanilla-sources-2.6.17.3 and gentoo-sources-2.6.16-r9
and both didn't work for me.

I don't think hal and dbus has something to do with this error,
since vanilla-sources-2.6.13.4 runs without hal and dbus, with no problem at all.

But, I will give a shot later.

I forgot to mention that I already tried gentoo-sources-2.6.17-r1 without hal &
dbus.
And no success, as usual.
I think I am getting used to the failure.

The dbus-0.62, hal-0.5.7-r3 plus gentoo-sources-2.6.17-r2 combination doesn't 
work for me (rest is x86). Like spiralvoice, I own a SCSI burner.

linux-2.6.18_rc2 has the same bug

@alwin: Please try to setup Gentoo ~x86 and try again, I can really
confirm that the bug is gone now. I believe it is connected to
some other app using kernel stuff which may have gotten updated to
deal with newest kernels in the meamtime.

The bug is definitely gone here with ~x86.
But I do not know which app could be responsible for this as you
already updated hald and dbus to ~x86.

I waited for the mystery packages to enter the stable branch, but Gentoo 
2006.1/x86 still contains the bug. So I tried the testing branch (~x86): made 
partition backups, then uninstalled a lot of packages to save compiling time. 
After upgrading and rebuilding all packages, the bug was gone! Still don't know 
which package(s) cause the bug...

Is the problem still happening for anyone with latest kernels?
Thanks.

Currently I am using Debian testing with Debian kernel package 2.6.21-2-k7.
I did not hit this bug for months now and also some tests I did right now
also did not show this bug.

Well, I have to correct myself, the bug still happens here with
Debian packaged kernel 2.6.21-2-k7:

while accessing the CD drive from a Windows XP session inside VMWare workstation.

It seems switching the CD-ROM to legacy mode in VMWare fixes the problem.
