Subjectide-mod removal oops - 2.3.3-ac2
When I remove the ide-module in 2.3.3-ac2 (I use it for my cdrom), I get
the following oops. I'll check if 2.3.3 has the same problem:


Options used: -V (default)
-o /lib/modules/2.3.3-ac2/ (default)
-k ../../../ksyms-2 (specified)
-l /proc/modules (default)
-m /usr/src/linux/System.map (default)
-c 1 (default)
-a - same as ksymoops (default)
