Great work.

OK, I've had a look at the native 3.10 kernel driver versus the driver 
in RHEL 7.2, and clearly RH have already backported a lot of patches to 
this driver since the native 3.10 kernel driver in RHEL7.0.

Thus I've taken the latest RHEL 7.2 driver from 
kernel-3.10.0-327.10.1.el7 and applied the above 2 patches. This will be 
available in the elrepo testing repository shortly as:


kmod-mpt3sas-0.0-1.el7.elrepo.x86_64.rpm
mpt3sas-kmod-0.0-1.el7.elrepo.src.rpm

To install, please do:

yum --enablerepo=elrepo-testing kmod-mpt3sas

and reboot

Then please test as you see fit to see if it fixes your problem. You 
should be able to confirm the new driver is running by running 'modinfo 
mpt3sas' and looking at the path in the filename field. Simply uninstall 
the kmod and reboot to switch back to the native driver.

Regards,

Phil
