Comment 5 for bug 1190295

On my system:

$ uname -svrmo
Linux 2.6.32-46-generic #108-Ubuntu SMP Thu Apr 11 15:56:25 UTC 2013 x86_64 GNU/Linux

$ lsb_release -a
Distributor ID: Ubuntu
Description: Ubuntu 10.04.4 LTS
Release: 10.04
Codename: lucid

The RAID 1 partitions broke since kernel 2.6.32-47 ("Continue to wait; or Press S to skip mounting or M for manual recovery")
Booting back into 2.6.32-46 the md devices are correctly set up and the system boots normally

PS: still present with 2.6.32-48
