| |
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.
