Please upgrade to the version in unstable and let me know if it fixes
your problem.  I expect that it will, due to the fixes for #550704 and
#574863.

Please also note that your problem is not IMO directly related to
Philipp Kern's original report here, which is about devices that really
aren't supported by GRUB *at all* right now.  For GRUB, it's best to
file a new bug report rather than piggybacking onto an existing one.  As
such, please do not close this bug if you find that the version in
unstable fixes your problem.

Regards,
