Something very strange lately.
I'm using Redhat Advanced Server 2.1

I have managed to do a few things recently.

1)
Upgrade the kernel to: 2.4.20-18.10.1

uname -a
Linux red 2.4.20-18.10.1 #1 Tue Jul 29 13:24:24 PDT 2003 i686 unknown

2)
Finally get the nvidia drivers to work.

3)
Reconfigure the firewire with Oracle OCFS. Change /etc/modules.conf file, and add:

options sbp2 sbp2_exclusive_login=0
post-install sbp2 insmod sd_mod
post-remove sbp2 rmmod sd_mod

reboot (I know. shutup.)

/usr/local/bin/rescan-scsi-bus.sh

What are all these bugs in dmesg? Are they anything to be concerned about? How to stop them from occuring?
