Public bug report changed:
Got the same problem - can't assemble because of busy devices.
mdadm --examine /dev/hde1
mdadm: No super block found on /dev/hde1 (Expected magic a92b4efc, got 00000000)
The raid was created on gentoo one and a half year ago, migrated to breezy beta without a problem.
Just kept the mdadm.conf and was happy.
Here on Dapper the mdadm init scripts fail.
With the default kernel of kubuntu flight5 (2.6.15-18-386) i even got a segfault for
mdadm --details --scan
but after updating to 2.6.15-19-686 it worked normally again - with no result.
I got it up and running by just using --build:
mdadm --build /dev/md0 --level=0 --raid-devices=2 --auto /dev/hd[eg]1
