Description Yasuhiko Kamata 2007-07-11 11:59:12 UTC

After upgrading grub package 0.97-62 to 0.97-66 from openSUSE factory, a Mobile-AMD(Athlon) based computer became to be unable to boot.
It seems to reboot while grub stage loading. None of grub messages (ex. "GRUB loading stage 2" etc.) appered.

Downgrading grub package to 0.97-62 can avoid this problem. This is a workaround.

This is the cpuinfo on that machine.

What happens on a fresh install of e.g. Alpha7 or later?
If it works, this is a duplicate of the broken update, If it still does not, there might be a compiler bug lurking, as the source code did not change.

Comment 3 Yasuhiko Kamata 2007-08-06 13:34:39 UTC

I've just tested Alpha6 and Alpha7 with new installation (both versions are newly installed), this grub problem was not reproduced and this computer booted up successfully.
So I think this may be caused by a broken update as you said. Thanks.
