That's on VMWare, right? Jason has seen the same issue:

 http://marc.info/?l=linux-kernel&m=145280623530135&w=2
 http://marc.info/?l=linux-kernel&m=145523785705624&w=2

 "Works fine on real hardware and KVM. Filed an issue with VMware and the fix
  is in the works."

Jason, what's the state of this?

Thanks,

Correct ESXi 5.1 patchlevel 3070626 (the two controllers are passed
through to the VM).

#1364088 — RE: [BUG] mpt2sas: driver init fails on kernel >=4.2 for 9211-8i IT

The last update we have from VMware is that the fix will be in 6.0p3/5.5p8 - both of which are targeted for a mid year release.

That's on VMWare, right? Jason has seen the same issue:
