RE: System "hangs" on kernels > v4.4-rc1 - mpt2sas problem?

[Luck, Tony]

I also see that mpt2 and mpt3 were merged, with mpt2 option still there
as a legacy driver.  Which should I be using?   My config file has these
MPT settings:

$ grep MPT .config
CONFIG_PREEMPT_NOTIFIERS=y
CONFIG_PREEMPT_NONE=y
# CONFIG_PREEMPT_VOLUNTARY is not set
# CONFIG_PREEMPT is not set
CONFIG_CB710_DEBUG_ASSUMPTIONS=y
CONFIG_SCSI_MPT3SAS=m
CONFIG_SCSI_MPT2SAS_MAX_SGE=128
CONFIG_SCSI_MPT3SAS_MAX_SGE=128
CONFIG_SCSI_MPT2SAS=m
