Hello,
below is an oops that happend on one of our servers last week. This oops was
still logged by syslog, but its seems this oops immediately followed another
oops which made the kernel to panick. The last oops could not logged anymore
by the syslogd and unfortunately capturing using a serial cable was also
disabled. But I guess the second oops is only the result of the first oops,
so anyone knows were it comes from or how to further debug it?
Thanks,
Bernd
