ORA-00600: internal error code after Linux update

Question

Hi,
I just updated openSuSE from version 10.2 to 11.0 using the online repositoties. It seemed to keep all of my Oracle 10.2 directories and files intact. The Listener starts just fine, but the DB starts and then disconnects...
SQL*Plus: Release 10.2.0.1.0 - Production on Mi Sep 17 16:41:12 2008
Copyright (c) 1982, 2005, Oracle. All rights reserved.
Connected to an idle instance.
SQL> ORA-00600: internal error code, arguments: keltnfy-ldmInit, 46, 1], [, ], [, ], [
SQL> Disconnected
I've checked /etc/hosts. It contains the exact same info as my archived copy (that I saved before updating Linux). My /etc/profile.local file is also exactly the same; all pertinent variables are exported. So can someone please give me some other reasons for why the DB would disconnect?
Thanks for your replies!

You can verify if your system can lookup its hostname using ping:
[root@cfengine ~]# hostname
cfengine
[root@cfengine ~]# ping -c 1 cfengine
PING cfengine (10.0.0.1) 56(84) bytes of data.
64 bytes from cfengine (10.0.0.1): icmp_seq=1 ttl=64 time=0.026 ms
--- cfengine ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.026/0.026/0.026/0.000 ms
Above example shows a hostname (cfengine) which could be resolved; a hostname is used and the ping utility was able to resolve the ip address (10.0.0.1). Please mind that the actual function of the ping utility is to test host connectivity using the ICMP protocol, but because ping needs to resolve the ip address of a hostname to do so, it can be used to see if a hostname exists. There are much other methods to do so.
[root@cfengine ~]# ping -c 1 nonexistent
ping: unkown host nonexistent
Above example shows a hostname (nonexistent) which could not be resolved.
If a hostname can not be resolved, the hostname should be made resolvable. The most easy way to do so is by adding the ip address and hostname to /etc/hosts:
[root@cfengine ~]# ifconfig | grep inet
inet addr:10.0.0.1 Bcast:10.0.0.255 Mask:255.255.255.0
inet6 addr: fe08::a00:27ff:fe40:ec86/64 Scope:Link
inet addr:127.0.0.1 Mast:255.0.0.0
inet6 addr: ::1/128 Scope:Host
The ip address, 10.0.0.1 in my case. Next, put this ip address and the hostname in /etc/hosts:
[root@cfengine ~] echo "10.0.0.1 cfengine" >> /etc/hosts
Try ping again to see if the hostname can be resolved:
[root@cfengine ~]# ping -c 1 cfengine
PING cfengine (10.0.0.1) 56(84) bytes of data.
64 bytes from cfengine (10.0.0.1): icmp_seq=1 ttl=64 time=0.026 ms
--- cfengine ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.026/0.026/0.026/0.000 ms
