Issues with GRUB 2.04 from experimental with GPT labels
Just as a heads-up: I have noticed problems with GRUB 2.04 from experimental
on SPARC machines with GPT partition tables (but not with Sun partition
tables). So, please don't update to GRUB 2.04 yet until we have figured
out what the problem is.
The issues shows as follows:
Loading Linux 5.2.0 ...
Loading initial ramdisk ...
ERROR: Last Trap: Data Access Exception
The problem does not show with GRUB from upstream, so I'm not sure yet
what the problem is.
In case you already broke your system, you need to boot with the installation
CD  into rescue mode and re-install the older version of GRUB (2.02).
