Ouch! Sorry, no, I have never seen this mapper problem before. Maybe someone here has and could advise?

I take it you're seeing the messages when running lilo, right? Can you visualise your partition table (fdsik/cfdisk/qtparted) without problem, or should we perhaps start suspecting a corruption there?

Also you could try booting off the CD with the other kernel revision (2.4 if you had been using 2.6, and vice-versa; check the <F2> help screen at boot time for the appropriate cheat-code).
