Hi!
I did some more digging. r351355 is ok, while r351356 is bad.  This is 
Warner's (CC:d) commit to add RST support to nvme, however, I'm using a 
ssd drive connected to ahci.

What happens is that the ses driver doesn't attach to the AHCI SGPIO 
enclosure.  This is on a laptop with an ssd (not an nvme) drive.  I have 
the same issue on another computer as well.  On the broken kernel, 
sesutil status complains about "No SES devices found", on the working 
kernel it reports "ok".
