stable/11 r321349 crashing immediately

[G. Paul Ziemba]

GENERIC kernel r321349 results in the following about a minute after
multiuser boot completes.

What additional information should I provide to assist in debugging?

Many thanks!

It’s an SM961, not PM951.

Trouble with PM961 in SuperMicro X11

[Stefan Bethke]

I have a fresh SuperMicro SYS-5019S-M and I’ve installed a Samsung SM961 
128GBB, which I want to use as a ZFS cache.

After installing 11.1-RC3, I’m getting the below errors during boot, and trying 
to read or write to it produces the same message.

Is there a tunable to make this work? A quick test with Windows did not show 
any issues.
