Thanks, I'll test that out in a bit.  Now chasing another problem
where the system crashes quickly on bootup.  4.2.x has been stable,
but nothing since 4.3-rc1 has successfully booted up and lasted for
me.

No idea why, and not looking forward to git bisect to try and figure
out since it's my home NFS server with home dirs and other data which
needs to be rebooted to check.

Linux kernels 4.3+ mess up MPT2SAS configs

2015-12-03 Thread John Stoffel

Hi,

I've got an LSI MPT2SAS controller in my home system, great board,
running well.  When I try to use kernels newer than approximately
4.3.0, the default Kconfig entry goes away because of what looks like
a merge of the mpt2sas and mpt3sas drivers.

In my hand made 4.2.6 config I have:

   CONFIG_SCSI_MPT2SAS=m
   CONFIG_SCSI_MPT2SAS_MAX_SGE=128
   # CONFIG_SCSI_MPT2SAS_LOGGING is not set
   # CONFIG_SCSI_MPT3SAS is not set

But when I pull down the 4.4-rc3 release and do:

make mrproper
cp /boot/config-4.2.6 .config
make oldconfig

I silently get my CONFIG_SCSI_MPT2SAS entry removed, and the
CONFIG_SCSI_MPT3SAS is still left unconfigured!  This is a pain when
you boot up and your home directory and other data files aren't
available...

> grep MPT .config
CONFIG_PREEMPT_NOTIFIERS=y
# CONFIG_PREEMPT_NONE is not set
CONFIG_PREEMPT_VOLUNTARY=y
# CONFIG_PREEMPT is not set
CONFIG_CB710_DEBUG_ASSUMPTIONS=y
# CONFIG_SCSI_MPT3SAS is not set

Can we please get this fixed so that moving forward this is setup
properly?

Thanks,
John
