Bug#384611: mdadm - loops if superblock is broken

[Bastian Blank]

Package: mdadm
Version: 2.5.3.git200608202239-2
Severity: grave

mdadm initscripts loops if a superblock is broken:

| mdadm: failed to add /dev/sdb2 to /dev/md/0: Invalid argument
| mdadm: failed to RUN_ARRAY /dev/md/0: Invalid argument
| md: invalid superblock checksum on sdb2
| md: sdb2 has invalid sb, not importing!
| md: md_import_device returned -22
| mdadm: failed to add /dev/sdb2 to /dev/md/0: Invalid argument
| mdadm: failed to RUN_ARRAY /dev/md/0: Invalid argument
| md: invalid superblock checksum on sdb2
| md: sdb2 has invalid sb, not importing!
| md: md_import_device returned -22

This is not cancelable and breaks the whole machine.
