Re: Repeatable hard crash with 2.6.0.test[123]

>> Please apply this patch, see if you can capture a decent trace.

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

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.  Options used
     -V (default)
     -k kallsyms (specified)
     -l modules (specified)
     -o /lib/modules/2.6.0-test3/ (default)
     -m /usr/src/linux/System.map (default)

Warning (read_ksyms): no kernel symbols in ksyms, is kallsyms a valid ksyms file?
No modules in ksyms, skipping objects
No ksyms, skipping lsmod
