nothing happened any more? hal didn't appear to hang at the time you started the
strace, but it hanged much later when trying to access your CD-ROM (I presume).
Did you enable DMA on your CD-ROM by any chance?
In any case, I believe that the Breezy version should be much more robust
against these kind of errors. Can you test the current live CD?
Thanks for the trace. So after seeing
open("/dev/hdb", O_RDONLY| O_NONBLOCK| O_EXCL| O_LARGEFILE
