Colleagues,
after markm's commit current fixit no longer panics. However, trying to mount
FixitCD it just hangs. Console switcher works, but no more. Again, it's 100%
reproducible on three very different systems with ATAPI CD/DVD drives. I
managed to get ddb ps from hanged system:
cd9660: RockRidge Extension
[- here hang lies -]
