[Bug 599664] Re: 10.04 boot problems on nvraid mirror

[Phillip Susi]

Those are not grub messages.  It appears that your kernel is booting and
failing to activate the raid array.  Can you post the output of "sudo
dmraid -n"?

Title:
  10.04 boot problems on nvraid mirror

Status in “dmraid” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: grub2

  From time to time grub2 hangs booting from my nvraid-mirror, telling
  me not to find /home. Rebooting the system mostly works to get the
  raid detected properly. Syslog says in case of not finding /home:

  This problem occurs by 1 of 4 times I try to boot to my linux system.
  Booting Windows works everytime ...
