I quickly checked my dmesg logs and I'm not seeing that particular message, could be that newer kernels only started warning about it? I'm not seeing any references to the scsih_get_enclosure_logicalid_chassis_slot() function in the code here, so there is obviously a newer driver in newer kernels. The scsih_get_* calls I do see is in mpt3sas_scsih.c and I'm not seeing (direct) calls to _config_request at all. At least it seems there is activity on the driver, which is always a good sign that someone is attending to problems. I'll queue an upgrade to 4.16 so long for when it's released in a couple of days/weeks. Kind Regards, Jaco
