Informal(?) sesX messages

Hi all, please CC me on reply as I'm not subscribed to this list.

I've got one of those Supermicro 72-drive monster machines, all ZFS'd up.
https://www.supermicro.com/products/system/4u/6048/SSG-6048R-E1CR72L.cfm

And before & after replacing a faulty SAS Expander and a pair of cables 
(gobs of WRITE/ABORT errors), I'm still occasionally seeing these kernel 
messages (in groups), and I'm not sure if they're benign, or pointing to 
a SAS expander event... or what. I admit, this is my first time dealing 
with a machine with SAS expanders, so I'm a bit out of my depth in 
diagnosis thereof.

Every now and then (couple times per week) I'll get messages like that 
for a number of drives, but not all, and not particularly specific to 
any particular drive - but always spinning rust, not SSDs. It seems to 
happen under high load, but I'm not completely certain of that.

- Smartctl is happy with all the drives.
- We've got redundant power supplies and have rotated them around, run 
with spares
- ZFS has logged zero checksum errors, many scrubs, massive 
writes/copies/send|recvs & bonnies later.
- The messages come when we're using either istgt, ctld, local 
bonnie++s, dd'ing 0s, or just scrubbing.
- Seem to only occur while there's regular activity on the pools, NOT 
when importing/exporting/snapshotting.
- Tried without SSDs connected, and with TRIM off, no change (saw a post 
from a few years ago with the older version of the LSI SAS card having 
some issues with that.)
- It's a new machine, we're still commissioning it, but plan to press it 
into service as a Vmware storage machine later next week
- I've compiled and fired up sesd, but haven't had any messages go by 
recently
- OS is on a pair of Intel SSDs using the motherboard's controller, 
unrelated/unaffected. Root on ZFS tho.

Do I have anything to worry about? Are these normal things to see 
popping up sporadically? Could this be a firmware bug in the expander(s) 
or with the driver?
I don't have any important data on there at this time, so 
data-destructive testing is possible right now.

Including bunch of info that might be helpful for dx.

Thanks for any advice/suggestion!

Myke
PS: Please CC me in your reply.
PPS: That's the kind of hostname you get when you don't give me 
something better, or tell me that you don't care ;)

(The device IDs are a bit skewed as I hot-rearranged a number of them 
(camcontrol stopping and reimporting the zpools), but it'll do it after 
a reboot as well.)
