boot messages (boot.msg)

hi
i am facing this problem on my OpenSuse11, Ubuntu 8 installation on my
system (however the same system with windows xp works fine)
I am attaching a boot.msg and pasting the part of error here!
The hardware is:
One HDD IDE 80gb
One SATA 300GB
One SATA 250GB
Sony IDE DVD Writer

Sometimes it works fine.. but on an average out of 10 boots,7 times it
generates an exception.. and 3 times works fine... When it work without an error, there is most likely a chance that system will suddenly freeze, at that happens most of the times!

My workaround for this error is that i turn off the dvd writer from BIOS, and then system loads fine, but i cannot access CD/DVD anymore! 

Thanks & Best regards
Tony
