Well I tried both the fixes in that blog post and neither of them work. It just 
drops into the BusyBox shell. No apparent behavior change.

Does someone know of a fix that works?

But I've run out of time to debug this problem I'm going to have to deliver 
this server in a broken state and with a RAID that isn't.
