Unable to burn DVDs with kernel 2.6.10

[Laurent CARON <lcaron@apartia.fr>]

Hello,

I switched from 2.6.9 to 2.6.10 today, and tried to burn a DVD.

Tried with my "normal" user account, and it does the same as in the root 
account.

Here are the messages.


growisofs -Z /dev/scd0 -R -J ~/sendmail.mc

Any clue?

Thanks
