Debug Kernel Question [message #35167]

I built a debug kernel to debug a kernel problem related to kernel crashes from a bug relating to the EXT3 file system. However the messages file doesn't contain any more information than a standard kernel lockup. Is there a setting I need to activate to get more information about file system problems?

Also - this computer is being used for backups and has a LOT of files and a LOT of hard links. I'm also using one of those Seagate 1.5T drives but I did do the drive bios upgrade. And I've moved the drive to different computers and the problem follows the drive. (Or the fact that I'm backing up running rsync and cp -al and it always dies during the backup)

Sure like to get to the bottom of this. Thanks in advance.
