Here is some more info:

/usr/sbin/pvdisplay 
  Couldn't find device with uuid '2adyAl-cmc6-kSXj-a7Nu-IPmg-YF0e-5ERd6y'.
  --- Physical volume ---

It looks to me that the problem is the PV Name: Unknown device.

Please, can anyone tell me what command to use to fix this?  I can't run any
kernel after 2.6.4-1.305.
