I want give you result of sas bus trace, but company do not give me grant permission of take data outside. I think sorry to you not give data of bus trace. Well, I can tell you what is happen. Environment: SAS HBA: Microsemi Adaptec 6405H/7085H (Other SAS HBA not happend.ex Broadcom 9300-8E Adaptec 1000-8E) OS: Fedora26/CentOS7.3 openSUSE Leap 42.3 At install OS,when format partitions, HBA send some commands to a SSD device(I don't know what command is send to a SSD device). When device's queue is full,it return "queue full" message to HBA, but it was sending other command to device. I think a situation remaining the same,so OS can not install to SSD device. This problem is SAS HBA continue sending command when receive "queue full" message, and kernel can not detect it.
