Using v11 on top of 3.18 and after generating some traffic on the
network as well as compiling code on ahci in parallel I ran into the
following OOPS. Any idea what exactly is going on?
>From a 10000 feet perspective it looks like two problems to me
1) Allocation failure doesn't get handled properly somewhere
2) We fail to allocate with order=0 - I don't see why

Using v11 on top of 3.18 and after generating some traffic on the
network as well as compiling code on ahci in parallel I ran into the
following OOPS. Any idea what exactly is going on?
>From a 10000 feet perspective it looks like two problems to me
1) Allocation failure doesn't get handled properly somewhere
2) We fail to allocate with order=0 - I don't see why
