Kernel panic on "cups" startup

[Toralf Lund]

My (Red Hat 9) system has started displaying a "kernel panic" message on 
the console, then freezing completely, when the "cups" service is 
started. Everything worked fine a couple of days ago, and as usual, I 
know of no setup changes made since then. With cups disabled, the system 
seems to operate correctly, except I can't print, obviously. There is no 
printer connected directly to this host; cups is used to print across 
the net. I'm not sure I can give you the exact error message, as it 
doesn't seem to be stored in the system log or anything.

Any ideas?
