[Bug 941874] Re: (fakeraid) root device not activated during boot

[apircalabu]

Apparently I have a related problem after an upgrade from 11.10 done using "do-release-upgrade". The troubled server has all the partitions on a software RAID 1. With the new kernel (3.2.0-24.37) it failed to mount the root partition, dropping to a busybox shell.  After booting the ol kernel I found there's no dmraid package installed on the server. Installing it also pulled kpartx-boot as dependency and now I have /usr/share/initramfs-tools/hooks/kpartx in place. update-initramfs appears to have generated a bootable initrd this time, but I haven't had the chance to test it yet.
Also, looking at the initrd images for 3.0.0-16-server and 3.2.0-24-generic I found there are no dmraid & kpartx related entries in 3.0.0.16 image.
Is it perhaps worth to have dmraid & kpartx-boot as dependencies for a basic installation? For some reason they were not installed previously. Should I file a new bug for this? I haven't found anything similar yet.
