** Description changed:

  I have installed Precise Pangolin Alpha 2 to a fakeraid stripe, but ubuntu 
fails to boot after install.
- When choosing recovery option, the boot process times out waiting for root 
device and drops to busybox shell. 
+ When choosing recovery option, the boot process times out waiting for root 
device and drops to busybox shell.
  Running "dmraid -ay" and exiting busybox resumes boot and it continues 
normally.
  
  I've added a script in /etc/initramfs-tools/script/local-top/ that run
  "dmraid -ay" as a solution.
  
  The problem seems to be with the dmraid-activate script.
  For example, it expects a device name without "/dev/" (e.g. "sda") however it 
is being called from /usr/share/initramfs-tools/scripts/local-top/dmraid script 
with the full device name ("e.g. "/dev/sda"). Fixing that didn't solve the boot 
issue since the the activate_array function in dmraid-activate does not seem to 
work either.
  
  There might also be antoher bug on line 100 in dmraid-activate (in the awk 
script):
-     # Heximal to decimal conversion array
-     for (i = 0; i <= 9; i++) hex2dec[i] = i
-     hex2dec["a"] = 10; hex2dec["b"] = 11; hex2dec["c"] = 12
-     hex2dec["e"] = 13; hex2dec["d"] = 14; hex2dec["f"] = 15;
+     # Heximal to decimal conversion array
+     for (i = 0; i <= 9; i++) hex2dec[i] = i
+     hex2dec["a"] = 10; hex2dec["b"] = 11; hex2dec["c"] = 12
+     hex2dec["e"] = 13; hex2dec["d"] = 14; hex2dec["f"] = 15;
  
  Element "e" and "d" appears to have been switched. I'm not entirely sure
  what the script is trying to do though.
