Comment:

 @luroh: I'm a bit surprised that you have to `co` twice. Could you provide
 a syslog of the continued KDL?

 @pulkomandy: I'm afraid, we do indeed need the kernel tracing to track
 this further. `SCHEDULER_TRACING` would be helpful as well, as I think
 this may be some kind of TLB invalidation issue in a situation where the
 thread is scheduled to another CPU after mapping the memory.
 `MAX_TRACE_SIZE` doesn't need to be that big. I guess 100 MiB should
 suffice.
