In one of my mails, I decribed why there are 2 bugs in the kernel.
Only one of them so far has been fixed. The sense data is still missing.

Oups, sorry I didn't read enough carefully!!!

Does someone know how to fix the sense data bug?

Thank you very much,

In drivers/ide/ide-cd.c:cdrom_end_request(), try to insert something
ala:

	if ((rq->flags & REQ_SENSE) && uptodate) {
                struct request *failed = (struct request *) rq->buffer;
                struct cdrom_info *info = drive->driver_data;
                void *sense = &info->sense_data;

+		if (failed && block_pc_request(failed))
+			printk("%s: failed %p\n", __FUNCTION__, failed->sense);

                if (failed && failed->sense)
                        sense = failed->sense;

                cdrom_analyze_sense_data(drive, failed, sense);
	}

in pseudo-patch form.

just add a len=%d to the printk line, and failed->sense_len as the
argument.

Does it show like this:

        if ((rq->flags & REQ_SENSE) && uptodate) {
                /*
                 * For REQ_SENSE, "rq->buffer" points to the original failed
                 * request
                 */
                struct request *failed = (struct request *) rq->buffer;
                struct cdrom_info *info = drive->driver_data;
                void *sense = &info->sense_data;

                if (failed && block_pc_request(failed))
                        printk("%s: failed %p len=%d  \n", __FUNCTION__, failed->sense,failed->sense_len);

                if (failed && failed->sense)
                        sense = failed->sense;

In that case, I got:

No it's my mistake, should be blk_pc_request(). Sorry about that.

You're not supposed too, but you are supposed to send me the dmesg
output after trying a burn! The patch changes nothing, it just dumps
some info that I need to the logs.

Shouldn't this be below the 2nd if() and then just test "sense" ?

Like

That makes sure, that you report what is analyzed later here:

The interesting part is whether failed has a sense attached, and if so

To avoid confusion, I made the patch. Would have been easier to do in

Hello,

sorry I didn't understood that I was supposed to do this...
I have recompiled with your patch, and here the result of dmesg:

cdrom_end_request: failed, sense ce68de20, len=0

cdrom_end_request: failed, sense ce68de20, len=0
cdrom_end_request: failed, sense ce68de20, len=0

Maybe I should add that, also under 2.4, it goes till 4 Mb and then stay
at 4 Mb for a long time (something like one minute) and then it
continues perfectly (with ide-scsi under 2.4).

Thanks, this is the info I wanted. The sense info has not been read from
the drive, it seems.

That is correct, I'll fix the 2nd bug tomorrow. The new SG_IO transport
is still so new that there are places where I know ide-cd will not do
the right thing wrt sense. In fact I don't think it will every copy
sense back.

I have no idea... About 3-4 years ago, I tried to convice some of the kernel
people to change this but as you see, it did not happen.

I thought it's obvious: It is most likely a problem caused by the broken 
bit #defines in the Linux kernel for the SCSI status byte. I assume that
status should be 0x02 instead of 0x01. In addition, I would guess that
for the same reason, a kernel instance did not fetch the sense data as
libscg should try to work around these Linux bugs if at least the first 
sense byte is != 0.

Sounds plausible. Patch attached. Anyone care to expand on _why_ these
status bytes are shifted one bit?

Possibly related...  I was using SCSI tape to back up my 2.5.59 system
the other day.  A media error was encountered, but the application (cpio
in this case) never saw the error and kept on trying to write to the bad
tape.  Fortunately, I caught it after only 40 MB of associated syslog
entries had been made.

Thanks for the patch.  I can now go back to "unattended" backup mode
(except for having to change tapes periodically) :-).

Joerg,

Then you are aware of the push/pull by one bit as linux does not set a
reserved place holder for bit0 in the status byte.  I have to agree with
you that it stinks and make decoding status codes messy when supporting
N-interfaces of the protocol.

Cheers,

I should try to cut SCSI CD's with the fixes for this stuff; sounds like
it'd affect generic SCSI I/O.

Can't burn DVD under 2.5.59 with ide-cd

[Gregoire Favre]

Hello,

after reporting this problem, someone pointed me that I should try
without DAO, I have tried this:

mkisofs -dvd-video -V $1 $2 | cdrecord-prodvd driveropts=burnfree -dummy -v dev=/dev/hdc fs=64m speed=1 -eject tsize={$SIZE}s -

And got this:
