Here is firmware rev of the onboard LSI controller I am using: Port Name Chip Vendor/Type/Rev MPT Rev Firmware Rev IOC /proc/mpt/ioc0 LSI Logic SAS1068E B2 105 01160000 0 I tried 2.6.32 kernel from Ubuntu 10.04 and then tried updating to 2.6.33 from mainline. I also then tried updating the mptsas driver to the latest off LSI's site, v4.18.00.00. Nothing seemed to improve issue. Problem is, for me has been, reading smart info fast enough, or long enough, eventually the command will fail. It tries aborting task, bus reset, and then host reset. This takes some amount of time. The pause is what I believe causes drives to sometimes drop off the controller. I am not sure what is to blame, but at least a work around is to go in the LSI controller's BIOS and set all the timeout values to 0. The default timeout value seems to vary depending on which 1068E card you have and which firmware is installed. After setting all timeout values to 0, I still have problem with ATA pass-through, but the drives no longer drop off the controller when I hit the pass-through bug. Also I have both WDC and Hitatchi drives. Both behave the same. BTW here is errors I get when running hddtemp, basically same as OP: [156291.890023] mptscsih: ioc0: attempting task abort!
