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:

Just to confirm, the propsed patch to st.c fixes the issue with 2.6.24-rc5 as well at 2.6.24-rc5-mm1 with access to my DLT tape drives. Thanks! John - To unsubscribe from this list: send the line unsubscribe linux-scsi in the body of a message to [EMAIL PROTECTED] More majordomo info at

Re: 2.6.24-rc5: tape drive not responding

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]

Jens A repost of this patchset, which adds support forchaining of sg Jens tables. This enables much larger IO commands, since we don't Jens have to allocate large consecutive pieces of memory to represent Jens the sgtable of a huge command. Right now Linux is limited to Jens somewhere between

Re: Linux-2.6.13-rc6: aic7xxx testers please..

Hi James, As a test, I dropped back to 2.6.12.1 and the drive hung again last night while trying to do backups, so I suspect that I might have controller or tape drive problems of some sort. I'll also try to go back to 2.6.12-rc6 as well and see how that works out. My next step is to try and

Re: Linux-2.6.13-rc6: aic7xxx testers please..

James Well, I suspect the tape is hanging the bus, from which no card James can recover. Blech, not going to be fun to fix this sucker. James Just to test this, can you try sending a bus reset with sgutils (from James the debain package sg3-utils): James sg_reset -b /dev/sg3 James Then remove

Re: Linux-2.6.13-rc6: aic7xxx testers please..

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

Hi Linus James, I've still got problems under 2.6.13-rc6 with my DLT7000 drive on an AIC7880 builtin controller. Here's the message I got in dmesg. My system is a heavily upgraded Debian/unstable with dual 550mhz Xeon processors and 768mb of RAM, dual SCSI busses. The annoying problem is
