Oh hai!

I have LSI SAS 9217-8i HBA and `rmmod mpt3sas` leads to multiple
backtraces if any disks are connected to the HBA.
Reproducible on vanilla 4.7.5/4.8.1/4.9-rc1 kernels (haven't tested on
another versions).

Full output (4.9-rc1 kernel, 3*Seagate ST3000NM0023 drives are
connected) is rather long and can be found here:

…and also on boot I have an error than can be related to the backtrace:

There is no such file in sysfs after boot completion.
