 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.
