>Description:
 I am using DVD-RAM with ATAPICAM. there is not any problem
to execute disklabel, newfs and mount /dev/cd0.
But I will write a file to the DVD-RAM, then kernel panics.
Before ATAng, I can write files, but now cannot write.

backtarace is here:

>How-To-Repeat:
Use ATAPI type DVD drive with ATAPICAM drivers. Write a file
to DVD-RAM media after disklabel, newfs, mount. 

>Fix:
sorry, I do not know how to correct it.
