Linux kernels 4.3+ mess up MPT2SAS configs

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: CONF

Hi, This looks to be a regression between 2.6.23 and 2.6.24-rc5, I'll try to bi-sect this and report more on it. Basically, when I bootup, I get a ton of errors in the dmesg log along the lines of: [ 215.007701] sym1: SCSI parity error detected: SCR1=1 DBC=1128 SBCL=ae [ 215.008145] sym1:

Hi James, Dropped back to 2.6.11.1 and it hung again. I was able to get the drive back by power cycling it and then doing the scsiadd to drop and re-add the drive. I then used the bacula 'btape' tool to run some tests. It seems to be just fine with regular files, but when it hit EOM, all hell
