Package: src:grub2
Followup-For: Bug #854568
User: debian-sparc at lists.debian.org

Control: reopen -1
Hi!
The currently included patch unfortunately misses one important
hunk from upstream. Without the hunk, GRUB is unable to properly
determine the OBP path [1] and the boot fails.
Could you update the patch to include this hunk? I'm attaching
an updated version of the sparc64 patch which I just verified
to work and fix the OBP path issue.
Sorry for the extra noise, but the hunk got lost in the large
number of changes necessary for sparc64 support.
Adrian
