What's up with cdrecord and 2.6.x kernel?

[bidi]

So I just went to try to burn an iso image to CD, and I always run "cdrecord --scanbus" before just to make sure my CD-R drive is still there (yeah, I'm a bit weird). But this time, instead of getting the list of available drives and their nubmers, I got this:

So is cdrecord incompatible with the 2.6.x kernel? I know the 2.6.x versions on longer need to do the whole "ide-scsi" thing at boot up, but does it completely screws with cdrecord?

Nha...
Cdrecord works better for me in 2.6 than in 2.4(no emulation needed).
Just give it a try and if it works, ignore all the rest.

PS: I never really liked cdrecord though...

[bidi]

Went to try it out and got the same thing:

As you can see it's almost the exact same error. I looked that the README file and tried doing what they say in it but I get another set of errors.

[jens]

bidi@DebLinux:~$ cdrecord -dev=0,0,0 slackware-10.2-install-dl.iso

Don't use a "-" before "dev=".
Are you doing this as root or as user?

[bidi]

I'm trying both as a regular user and root... I keep getting the same error, doesn't matter what I do! I've even reinstalled it, but still get the same thing.

[jens]

What does it tell if you do:

cdrecord -v speed=4 dev=0,0,0 slackware-10.2-install-dl.iso

It's "dev=" and not "-dev=".
The "-v"(verbose) option could tell you more...

[bidi]

Same exact set of errors...

Oh, and I'm not using the "-".

[jens]

Strange, I've only seen this in 2.4 myself:

cdrecord: No such file or directory. Cannot open '/dev/pg0'. Cannot open SCSI driver.

I think it had someting to do with the boot loader... (but I don't see how this would make sense in 2.6).

I have it working at work, but can't access that system before next week(I'm sick).

You could try k3b, it usually gives better error messages than just cdrecord...

Try using cdrecord as root,
there are some issues with 2.6.* and rights.

Do you have a 'normal' IDE cdburning device, or do you have a scsi device?
In case you have a IDE device, you can use ATAPI in you cdrecord command.
cdrecord dev=ATAPI:0,0,0 <more options>

[bidi]

I still got nothing. The same error.

I think the important line is the one that says "No such file or directory. Cannot open SCSI driver". Seems like I need a file /dev/pg* and it obviously doesn't exist.
