I have seen this problem on my LC475 also. As I haven't seen it on any
of my other Macs, I thought it was a hardware problem with my LC475.
It's interesting to hear others have the same problem and that it's
limited to the 475/605 boxes (which are essentially identical
motherboards). Dana if you happen to remember what this is related to
it would help me in tracking down where/how to handle it in the kernel
code. Could it perhaps be related to memory? The frequency of the
messages seemed to increase when I upgraded from 36 MB of RAM to 68 MB.
