Hi,

have you checked, that cdrecord is not suid root, and growisofs/dvd+rw-tools 
is?

I had some probs, solved with a simple chmod +s growisofs :)


Glück Auf

Lucky you. Burning as root here, cdrecord not suid. Tried also
 burning with a +s growisofs, but...

You can test if it's the kernel/growisofs clashing by hacking the
drivers/block/scsi_ioctl.c  code

It's around line 193 in 2.6.9, and line 196 in 2.6.10
not sure about 2.6.11

find the code:

        /* Write-safe commands just require a writable open.. */
        if (type & CMD_WRITE_SAFE) {
                if (file->f_mode & FMODE_WRITE)
                        return 0;
        }

edit it to something like:

        /* Write-safe commands just require a writable open.. */
        if (type & CMD_WRITE_SAFE) {
                printk ("Write safe command in ");
                if (file->f_mode & FMODE_WRITE)
                        printk ("write mode.\n");
                else
                        printk ("read mode.\n");
                return 0;
        }

Compile the kernel with that and that may make it work and burn dvd and let 
you know if it's growisofs sending incorrect commands. You'll get messages in 
dmesg like

Write safe command in read mode.

which means growisofs is still not right. Maybe later version fixed this?

As with the original report, the drive is sending back a write error to
the issuer. Looks like bad media.

I'm definitely unconvinced about the possibility of bad media...

Retrying the burn process works, sometimes on first attempt,
 sometimes after tray reload, and all checksums from original
 files to the burned files are just okay. This happens with different
 discs from different brands.

So far I had *one* bad disc - that would keep the light on my
 DVD burner blinking forever until I hit the eject button, and
 made my laptop (2.6.11-rc2-bk1) DVD player barf:

Jan 24 03:02:13 incident kernel: ATAPI device hdc:
Jan 24 03:02:13 incident kernel:   Error: Not ready -- (Sense key=0x02)
Jan 24 03:02:13 incident kernel:   No reference position found (media
may be upside down) -- (asc=0x06, ascq=0x00)
Jan 24 03:02:13 incident kernel:   The failed "Read Cd/Dvd Capacity"
packet command was:

00 00 00 00 00 "



Earlier FC3 kernels had another problem (that now isn't surfacing
 anymore) that I described on the cdwrite list:

The error is quite clear, sense 0x03/0x0c/0x00 is write error with no
additional specification of what kind. It's 100% certainly a drive
generated error, and I don't see any way that software is involved
there. Sense key 0x03 is a medium error.

Could be dirty drive, perhaps it needs cleaning?

Could also be a focus problem.

when i do the following:
1: get a brand new 25pack box.
2: burn with my 2.6.11-rc1-bk9, and it fails
3: boot 2.6.9-rc1 and -rc4, and it works perfectly
i find it extremely unlikely that the dvd's (of the same pack) i try on
a newer kernel than 2.6.9-rcX just happens to be the faulty ones..
especially since other persons report aswell..

i got the latest version, and i just did this, nothing of this appeared
in dmesg, but also, i dont see what scsi_ioctl has to do with anything?
i dont use scsi emulation

Perhaps some command earlier is being rejected which causes this later
hardware reported error due to some setting being different? It could be
something like that, one thing is for sure - the error generated as
displayed _is_ a media error and it _is_ being generated by the
hardware.

Someone suggested logging possibly rejected commands, I think that would
be a good idea to try.

it doesn't have anything to do with ide-scsi scsi emulation,
direct-to-device SG_IO uses drivers/block/scsi_ioctl.c (note the block/
directory, not scsi/).

strange that it doesn't catch anything...

I've got several reports like this that only happen with ACPI, and one
user whose burns report fine but are corrupted if ACPI is allowed to do
power manglement.

Really weird, I cannot begin to explain that. Perhaps the two reporters

I can sort of guess - the CPU frequency changes (either from ACPI or
perhaps also from cpuspeed if in use ?) involve the CPU disconnecting
from the bus and reconnecting. There is much magic involved in this and
there are certainly chipset and CPU errata in this area.

Well, booted into 2.6.11-rc2-bk2 (ACPI config'd out) and my
 first growisofs session decided to die at 60% with the usual EIO :/

The fun thing is that retrying now shows growisofs calling a
 HUGE amount of these babies...

Now of course, after Ctrl-C'ing the growisofs session, a new
 attempt yielded this

Only thing I note is that after reloading, the WARNING about

I guess my next move will be borrowing a Windows CD and
 installing it on my former RedHat 9 partition, then trying
 to burn DVDs from there...

I disabled cpufreq in the kernel, acpi i still have in kernel.. when i
booted i did acpi=off, and changed IO scheduler to anticipatory

caused it. but im glad.. i still have the small change in scsi_ioctl.h,

That's interesting, a short io starvation could for sure cause it. I
would really appreciate if you could try one change at the time though,
right now it's not really clear if it's acpi or the io scheduler.

well.. all good things must come to an end.. the second dvd i burned
failed.. :(
this is really frustrating.. but im pretty pretty sure its not media
error..
perhaps i must reboot after each burn again.. anyway, it is nice knowing
everything isnt completely lost :)

i just rebooted, (and booted with acpi off, anticipatory like before)
and burned a DVD, and it works.. this means that when acpi is disabled,
cpufreq off, i have the same problems i initially had with earlier
kernels (2.6.9-rc*)

that is: i could burn 1 dvd, which works fine, then the next i burn
fails, with io error, then the third i burns works.. in short, every
second works.. unless i reboot after each, then no one fails..

its a insanely strange problem. :) but atleast im able to get abit free
hd space now :)

FWIW, I happen to experience the same with the latest
 FC3 kernel on my Samsung TS-H552 burner; that is,

1. CD burning works 100% of the time
2. DVD burning may fail with EIO (nothing in kernel logs)
3. retrying burning usually works

Yes, I resorted to only use DVD+RW media now since the
 ratio of coasters has made +R more expensive than +RW :(

Last night I had to insist quite a lot with my burner's eject
 button before it decided to open and let the disc out (this
 particular session after failing once at 61% with EIO would
 reliably fail at the initial write). After reloading the tray
 with the same disc, I successfully burned it.

NB - this happens with Memorex and Verbatim media,
 not with el-cheapo discs.

I'm available for eventually testing of the 2.6.11-xx kernels
 from kernel.org (another side-effect of moving from RH9
 plus kernel.org kernels to FC3 and its own kernel is that I
 no longer have a dead machine after the updatedb run,
 which would happen about twice a month on my 256MB
 RAM k7-800).

DVD burning still have problems

[Kasper Sandberg]

hello, i followed the last thread, "unable to burn DVD", and there was a
patch, which was said to work, but it does not.. (i am running
2.6.11-rc1-bk9)..

the problem started around 2.6.9 (or something like it), when i was only
able to burn 1 dvd, then i had to restart before i could burn another
(or every second dvd i burn would fail), the error i get is input/output
error.. my burner is working perfect, since it works on windows, and on
2.6.9-rcSomething.

it is not a specific place in the burning process it fails, sometimes at
10%, and sometimes at 97%

burning normal cd's works perfectly

now on 2.6.10 and 2.6.11-later i cant burn dvd's at all, every time i
try to burn one, it fails, i have tried different speeds and media, same
thing, i got a Liteon sohw1213S dvd duallayer burner, allthough im not
using duallayer media.

here is a log from a burning i just tried:
