Thanks, the patch makes things a lot more rational :-) Attached is the ksymoops output from my "java-exit" panic. Let me know if there is anything more I can do to help solve this one =S.Coffin GV Computing scoffin@comcast.net ps= why the warning from ksymoops? Is there some mismatch between the kallsyms file format and the ksymoops expected format? I no longer have a "ksyms" file in /proc.... =========================================================================== ksymoops 2.4.9 on i686 2.6.0-test3.
