Re: cd burning problem

[Joris Huizer <jorishuizer@planet.nl>]

Hello,

Because I thought the problems might have been caused by a mistake I 
made with the 2.6.8 kernel, I compiled a 2.4.27 kernel and setup scsi 
emulation again;
Now, cdrecord can see the emulated scsi device:

      The original author should not be bothered with problems of this 
version.

But cd burning won't work; This error log shows nothing changed by the 
(huge!) move to scsi... (trying to blank the CD)

Can anyone tell what causes this error -- and what to do about it? It

`dmesg` doesn't give anything special, it just ends with the scsi stuff,

I tried to search on this but I haven't been able to find solutions for 
this problem...

I hope you can help,
