Thanks. Typing 'old' at yaboot prompt did the trick.
Tab gives two kernels to select old and kernel (new). The delay at yaboot prompt is quite short and did not realise that chance for user input there as first tried to boot a few time. It is not like a lilo or grub boot selection screen used to on PCs. It seems to boot ok, and as you say sound does not work. But am relieved to have it working with virtually every thing major seeming to work ok, I guess not much change in interface functionality for incremental kernel change -- 2.6.15 kernel fails to boot on ppc machine https://launchpad.net/bugs/34508 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
