It is okay, after moving PUPA into GRUB2. For now, don't change it.

You should see the archive of bug-grub. The problem is that Linux does not 
synchronize caches for partitions with caches for disks correctly. So if you 
access a disk by opening the whole disk, it could produce a cache-incoherence 
problem. That's why it is necessary to open partition devices only on Linux. 
Because this problem is about caches, you cannot always reproduce it.

I didn't know this! Thanks for this information.

The file "stage1/stage1.S". AFAIK, only this file.
