SubjectRe: test12 lockups -- need feedback
Here we go folks. I hope I got everything right. The only place I have a
doubt is the 0010: part of EIP. I couldn't read what I wrote there.
Looks like it's ip fragment related?

ksymoops 0.7c on i686 2.4.0-test11. Options used
-V (default)
-K (specified)
-L (specified)
-o /lib/modules/2.4.0-test12 (specified)
-m /usr/src/linux/System.map (default)

No modules in ksyms, skipping objects
invalid operand: 0000
CPU: 0
EIP: 0010:[<c01e610e>]
