Oh! Glad to see it was not just me suffering from this bug. Still
running a patched 4.0.0 kernel through the SAS expander. Everything
seems happy.

Tested against main RAID6, 7 disk array, with sas extender and work
with out error.
Tested against 2X mirror of SSD's, direct attached, and worked with out error.
Check was a simple RAID check. "echo check > /sys/block/md126/md/sync_action"
Patched against:
root@nas:~# uname -a
Linux nas 4.0.0 #
Oh! Good idea. ;-)
I will test it in 6~8 hours, once the raid check finishes.

Wow, I forgot how long it takes to compile a full kernel. Glad I ran
Gentoo for a few years and knew how to compile and apply patches. I
will admit I had to dust off some mental cobwebs.

Well, that narrows it down. It looks like there's a longstanding bug in

Any chance you can capture a vmcore (kernel only pages), I will
provide an upload location.

Removing the sas expander and attaching the SATA drives directly works
just fine. I had to limp along with the drives direct attached for a
while, while debugging.
Here is the dump from: Linux version 3.15.1-031501-generic. Just tested it.
