SubjectRe: test13-pre4... udf problem with dvd access vs test12
Jens, I made sure to reverse the udf patch I mentioned in another thread
(all it really is merging changes from linux-udf cvs into the current
kernel). So this is from a clean test13-pre4 w/ some netfilter fixes.

ksymoops 0.7c on i686 2.4.0-test13-pre4. Options used
-V (default)
-K (specified)
-L (specified)
-o /lib/modules/2.4.0-test13-pre4/ (default)
-m /usr/src/linux/ (default)

No modules in ksyms, skipping objects
