[BlueOnyx:13549] Re: Crashed drive

[Gregg K]

Sorry about the lack of information earlier, I wrote from my phone.  It is
stalling with the kernel panic when it's trying to load the LVM volume.  On
a rescue cd I can't see the hard drive.  I assume the the LVM volume is
corrupt, it won't load the /home directory.
