Please find attached all the /var/log/dmesg* files with their timestamps 
in ls.txt .

But about the firmware warning in the initramfs environment - is it 
really useless ?
Cause all the other roundabout 100 modules did load successfully using 
"modprobe -d /mnt" after mounting the harddisk /dev/sda8 at /mnt .
Doesn't that mean that the radeon driver does not evaluate some 
environment settings but instead uses some fixed path settings - which 
might be wrong under certain circumstances?
