Bug#430011: partman-partitioning destroys MBR partition table on macbook.
Package: partman-partitioning
Version: 50
When I wrote the changes to the disk in partman, it wrote a wrong partition
table to mbr. Even if I did not any changes (except setting a partition as
a mountpoint and formating the swap space) in the partition table.
The problem appeared two times I tried it.
Even when the mbr partition table was corrupted, it was able to read it
from GPT. But when writing to disk, it wrote the same corrupted table (it
seems that It wrote only the first partition record, but with the end
cylinder set to the end of whole disk)
I used the snapshot of netinst CD of Debian testing for the amd64
plattform.
This is my hexdump of the MBR partition table after recovering it. I am not
able
to post the corrupted table now.
