CD track description for cdrdao
Description of problem:
After reading a CD which contained bad data kernel crashed when trying to unload
scsi-mod module. This happened after I was trying to read a CD written on
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. download attached foo.toc
2. dd of=foo.bin bs=150k count=0 seek=10
3. insert a blank CD-RW into USB CD writer
4. cdrdao write --device 0,0,0 --buffers 10 foo.toc
5. wait for cdrdao to finish with error
6. cdrdao read-cd --device 0,0,0 --datafile xxx.bin xxx.toc
7. wait for cdrdao to finish with read errors
8. turn off CD writer
9. modprobe -r sr-mod usb-storage
It should unload specified modules
I've tried my best to reproduce that broken CD, but with the real CD kernel
oopsed with different diagnostics just after I've turned off the writer's power.
That looks very similar to recently fixed bug with pulling off USB writer's cable.

previous kernel, it's possible your bug has been fixed already.
Please retest with this update, and update this bug if necessary.
