CDRW Ricoh MP7083A crashing the whole system

[Pierre Thibault]

Hello,

It appears that the CDRW drive that I have is crashing my whole Linux 
system. It is a Ricoh MP 7083A.

At first, I was trying to install Kubuntu on my machine using this 
drive. I was able to start the process but while booting I had a system 
crash at 'Mounting the FileSystem'. I does this each time whit this drive.

So what I did to solve this problem is to add another drive to read the 
live CD of Kubuntu. Using this second drive, I was able to install 
Kubuntu without problem.

But now when I insert a disk in the Ricoh drive, it crash the whole 
system. I've tried with both an audio CD and a CDRW disc. The result is 
the same, a few seconds after the disk is inserted, the whole system 
crash without giving any feedback (the usual dialog asking what to do 
whit the CD does not appear). It freezes. My other CD drive works perfectly.

Another thing that I did is trying to boot while inserting an audio CD 
at the startup. It start to boot and it crash at the hardware abstract 
layer loading process.

If I look at my fstab file, I have no line for the Ricoh drive. Another 
weird thing that I notice is that both 'cdrom' and 'cdrw ' in /dev are 
pointing to 'hdd'. Remember that I have another CD drive on my system.

I made a search about this problem and I found this interesting link:

http://kerneltrap.org/node/4351     (Search in the page for 7083)

I don't know what to do from there. I hope this report will be useful.
