Live CD problems.

Hi,

During boot of the live cd this shows up:

Later on, if you start the installer and try to install, or issue
something simple
as 'pwd' this happens:

dscheck(#acd/2): attempt to access non-existant partition
dscheck(#acd/2): attempt to access non-existant partition
vm_fault: pager read error, pid 830 (csh)
pid 830 (csh), uid 0: exited on signal 11 (core dumped)

Here's dmesg.boot:
