|  As I write this, I am waiting for a NetBSD 6.x/amd64 machine to finish
|  a crash dump.  I have plenty of time to write, because it's dumping at
|  a rate of about 1 MB/s, which means dumping 16 GB of RAM is going to
|  take more than four hours.
|  
|  As in the case of the original bug submitter, the dump target is a
|  Seagate SATA disk.
|  
|  I will bump the priority of the PR, because this bug is now affecting
|  multiple users and is a serious impediment to the diagnosis and fixing
|  of kernel crashes.

Are sparse dumps enabled and working?
