this is the bug information
so if someone will help me i will be thankfull to him/her
a first suspicion is that the bug maybe related to bad cd media (did you run
linux mediacheck on your CDs?) ... but it may be another issue and we are trying
to reproduce the problem internally to understand what is going on ...
