Kernel msgs (errors?) in Logwatch since restore from backup

Hello all,

I've been running a Debian Lenny LAMP server since last Sept and have been very happy with it. Linux has always been a hobby for me and most times I run up against something new, I can figure it out with a bit of googling. Something has me stumped though and I'm hoping you guys can shed a little light on the situation.

Around May 5th I accidentally deleted something important from my server. In order to get it back, I restored my server from the most recent nightly backup. Ever since then, in about 95% of my daily logwatch reports, I have loooooong list of kernel messages. Logwatch doesn't call them errors, but they very well could be. I never had stuff like this in my reports before the restore, but now it's almost every day.

Here is an example of the output:

I had to add all those line breaks by hand, so hopefully I found them all. :)

Anybody know if this is something to be worried about? How to make it stop? Why a restoration would cause this?

Your thoughts are greatly appreciated.

Thanks in advance.
