Sorry for the VERY long latency.  Started Joyent last week, attended a funeral yesterday, and more.

I apologize if I'm missing something.  Here's my home system:

The INTEL drives are 512b sectors.  The HGST drives (which are NOT boot disks) have 4kb sectors.  zdb shows this with ashift.

I thought this problem manifested with ANY 4k disk on your system, even if it wasn't the boot drive?!  Or am I missing something from the back discussions?  And yes, this server boots with Loader (off a old-school Solaris-partitioned INTEL SSDs).
