Re: [BUG] mpt2sas: driver init fails on kernel >=4.2 for 9211-8i IT

Hi Sreekanth,

thanks for digging into this issue. Regarding the 4.5.0 after 4.1.20
boot statement, I will try to express myself better:

I first started the system with the 4.1.20 kernel. Then I issued an
'init 6' warm-reboot and chose to boot the 4.5.0 kernel. This procedure
often works (i.e. I'm able to boot the newer kernels (>=4.2) this way
with mpt2sas initializing just fine).

I will try the msix_disable parameter and report back. Maybe kernel
version 4.2 broke interrupt handling somehow?
