kernel 4.8.6 .config
I'm not sure whether this is a SCSI / HPSA bug or a networking / tg3 driver
bug. Both are seen in the stack dump. As the trigger seems to be HPSA I'm
reporting as a SCSI issue here...
I've been recently attempting to run mainline 4.8.x kernels, most recently
4.8.6, on our production HP DL 380 Intel servers.
On several of them there is some related issue reported in
https://bugzilla.kernel.org/show_bug.cgi?id=187221 where the HPSA driver on
some of the hosts sometimes resets the logical device. I had seen that already
with 4.4.x kernels, and again with 4.8.6.
Now, specifically with 4.8.6, on the box which has the worst of these symptoms,
I _additionally_ experienced multiple full kernel panics. The same box (with
the same hpsa reset symtoms) had been running 4.4.x kernels before without such
kernel panics. The panics then happened multiple times with about a day in
between.
On the last round I had the ILO SSH console running under screen with logging
enabled, and was able to retrieve the following panic backtrace:

I'll attach my kernel .config.
As this is a production system and so far the panics only hit with our usual
(webserver and DB kvm machine) production load active, there's not much testing
or bisecting I can do, but I didn't want to drop the issue unreported, either.
Hope this helps somebody. If there is any more info I can provide, just ask
what would be useful.
(I'm back to running 4.4.x)
