It may have been - I didn't catch the initial cause of the problem in my log because it hard-hung the VM and it wasn't in the scrollback buffer on the console. All I saw was a corruption error, a shutdown and the stack blowing up. Still, I think there is a real problem here - any persistent device error on IO submission can cause this problem to occur....
