Thanks.
It looks like there's also an out-of-tree driver available, if people
want to go that direction. (For example, it's available from Dell at
https://downloads.dell.com/FOLDER04588242M/1/UnifiedDriver_7.700.52.00_SLES12.tar.gz

Are the patches for 4.4 (Xenial) available somewhere? We'd like patches
so we can build the kernel ourselves. We can immediately do basic
testing against H730/830 (Invader, previously supported) and H840
(Harpoon, new, probably same as H740 except with external connectors
instead of internal). With

Yep, that fixed it. stress -c 8 is now using all 8 CPUs. Please cherry-
pick upstream commit 728e5653e6fdb into Utopic. :-)
Just for posterity, I'm attaching some instructive dmesg output. This is

Let me know if you need additional info.
