Bug Description

Binary package hint: mdadm

A clean install of Lucid AMD64 Desktop version on a single partitioned disk, without any raid devices, ie simple primary partition. System installs OK and is then fully updated. reboots correctly after updates without problems.

open a terminal and......

$ sudo -s
# apt-get install mdadm
# reboot

renders the machine unable to boot, after a moderate wait it drops to the initramfs prompt.

Again this system has no raid devices. root is a simple ext3 (/dev/sda1) partition, only other partitions is a single swap.

I had read through that bug and originally didn't think it was the same. Since then, I have tried to reproduce the issue on a "factory fresh" disk and it boots correctly. Previous installs were on old nv-raid drives, booted with the -dmnoraid kernel flag.
I'll add my results as another data point to the #158918 bug.

Thanks.

Does affect me as well - here are the steps to reproduce:
Fresh install of Ubuntu Desktop 10.10, performing all online updates - reboot works fine. Then install mdadm the system does not boot any more:

mount: mounting /dev/disk/by-uuid/.... on /root
failed: Device or resource busy
...
...
No init found. Try passing init=bootarg.
