Subject: [2.6.9-rc1-bk14 Oops] In groups_search()
Date: Thu, 09 Sep 2004 10:54:06 +1000 [thread overview]
Message-ID: <413FA9AE.90304@bigpond.net.au> (raw)
[-- Attachment #1: Type: text/plain, Size: 554 bytes --]
This problem also existed in bk12 but not in the base 2.6.9-rc1. (I
don't know about other bk versions as I have only tried these two.) It
is triggered by gdmgreeter and gdm-binary. System being used is Fedora
Core 2 on an UP i386 machine. The system survives the Oops and is still
usable.
Output from syslog and the results of running ksymoops on that output
are attached.
