Subjecttest13-pre4 ip defrag oops
Just got an oops uner test13-pre4 when I tried to access a new nfs
export. Looks like the ip defrag monster doesn't want to go away =)

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
