Kernel error - should I be worried ?

[Mahesh Padmanabhan <mahesh@cgi.com>]

Here is the error that I get (modified snippet from boot 
message below).

I upgraded from a base slink distribution to potato. The upgrade
process indicated that I should get rid of portmapper from the
startup files manually. I did that but still this message won't
go away.

I am not even sure that portmapper causes this. 

Any ideas ?

Thanks.
