Hi,This behaviour is reproducible with less partitions in scheme partition. I tried with this:
| Partition | Tipe | Mount point | Space | | sda1 + sdb1 | Primary - ext3 | / | 10 GB | | sda2 + sdb2 | Primary - swap | swap | 1 GB | | sda3 + sdb3 | Primary - ext3 | /chrut | 4 GB | | sda4 + sdb4 | Primary - ext3 | /var/log | 1 GB | and debian-installer exits when configuring RAID. Regards, Xan.
