After copying any data to dvd-ram media, copying seems to be too fast ( about 
30MBps ) for few seconds. It seems that data are cached
somewhere. After few seconds, system freezes and there is no chance to login or 
do something with it. Openssh daemon will kill opened
sessions and machine is reseting any tcp connections coming. Icmp echo 
survives, it is possible to ping that machine after crash.

Problem occured after installing ( clean installation, not upgrade ) edgy 
instead of sarge.

Maybe it should be kernel problem. (?)

Yes, it is bound to be a problem with the drivers for your device, or 
another part of the kernel. udftools is only the userspace portion.

Try upgrading to the latest kernel - maybe use a kernel from kernel.org, 
Debian always lags a bit.

Please close this bug, the udftools userspace tools do not (directly) cause 
the crash.

Cheers,

  Richard
