Package: mdadm
Version: 3.0~devel3-1
Severity: grave
Tags: upstream
With mdadm 3, the initrd hangs after the mdadm hook ran:
Begin: Mounting root file system ... + pre_mountroot
[...]
+ call_scripts
+ [ = y ]
+ /scripts/local-top/mdadm
[...]
Begin: Loading MD modules ...
Success: loaded module raid1.
done.
[...]
Begin: Assembling MD array /dev/md0 ...
Success: started /dev/md0
done.
[... hook returned ...]
+ [ -e /conf/param.conf ]
+ [ n != y ]
+ log_end_msg
+ [ -x /sbin/usplash_write ]
+ _log_msg done.\n
+ [ n = y ]
+ printf done.\n
done.
+ wait_for_udev 10
+ command -v udevadm
+ [ -x /sbin/udevadm ]
+ udevadm settle --timeout=10
[... here it hangs forever ...]
If I downgrade to mdadm 2, the problem goes away, which leads me to
believe this is something related to the new way mdadm 3 interacts
with udev.
