I'd say it is a Linode problem, unless you run custom kernel modules.
It looks like a "memory" corruption to me and since it is virtualized 
system, you should check if host system is ok.
Memory in quotes because this issue could be also related to a storage 
sub-system (local or network attached) of the host or VM.
