Just wondering if anyone had the same problem, and posting for reference. Unfortunately as I have only two PCs available at the moment both in daily productive use, I cannot afford to do much pre-release testing, but yesterday I did upgrade one from 11.4 to 12.1. It is a dual-boot (with Windows XP) Dell Inspiron 1300 laptop. After upgrading, GRUB could not boot into openSUSE, with an error message like "could not mount root partition". The partition layout had not changed in the upgrade process, the root partition was /dev/sda6 on the only hard disc in the machine. GRUB's entry had been renamed to "12.1" so the upgrade obviously did *something* to GRUB. I apologise for not having saved menu.lst at various steps in the process, I was too keen to fix it. Which I did with the excellent Swerdna's instructions here: http://opensuse.swerdna.org/susebootfive.html#brokengrub ...which let me boot into 12.1 for the first time. Then I autoconfigured GRUB from scratch with YaST, and everything worked normally.
