error since moving to marvell kernel - BUG: Bad rss-counter state
Hello All,
Today I tried again to run linux-image-marvell (4.7.0-0.bpo.1 in this
case) on my QNAP TS-221. I had issues with it in the past but did not
get around to file a bug.
I have the same version on a TS-219 which is running fine.
Booting the TS-221 generates two types of error messages.

Running the TS-221 on linux-image-4.3.0-0.bpo.1-kirkwood is very stable.
As said, running the TS-219 on linux-image-4.7.0-0.bpo.1-marvell is also
stable.
Main differences I see between the TS-221 (unstable with 4.7 marvell)
and TS-219 (stable with 4.7 marvell) are:
* the kernel flavor,
* the SoC and
* unencrypted raid (TS-219) versus encrypted raid (TS-221).
I am unsure if this is hardware related or setup related and also do not
know how to further analyze this issue.
Also not sure if this should be reported as a bug or not.
Any help appreciated.
GRTNX,
RobJE
