I can't get the SES device on my MPT controller to show up in Linux as a sg device. The controller is a re-flashed IBM BR10i (LSISAS1068E), running the latest firmware and it is connected to the SES capable backplane via i2c on the SFF-8087 sidebands. Bios post as follows: SLOT ID LUN VENDOR PRODUCT REVISION SIZE \ NV --------- ----- ------- --------------------------------- ------------------------------ --------------------------- ---------------- 8 0 0 IBM SAS SES-2 DEVICE 01.0 8 1 0 IBM-ESXS ST973401SS B51D 68 GB 8 2 0 IBM-ESXS ST973401SS B51D 68 GB 8 LSILogic SAS1068E-IT 1.33.00.00 NV 2D:03 Windows 7 reports the device present in device manager.

Is there anyone here who wants to help me get the raw SES device to show up as a /dev/sg<x> so I can use the sg_ses (sg3_utils) commands to control the leds and get environmental readouts? I'll apply any patch you can come up with for the sake of getting support into the kernel.
