Hi Himanshu, Today I tried several times and have some news. Before I insmod the qla2xxx.ko , if I shutdown then start the FC switch port connected to the HBA card, the qla2xxx.ko works well. It seems that the issue has relation to the FC switch port. Maybe some old status causes the issue. The FC switch model is H3C S5820V2.

From the syslog that you sent me, I do see driver version 10.00.00.02-k which is from 4.15.0-rc6 so atleast you are using the correct driver. (in your email earlier you mentioned 8.07.xx which was confusing) Jan 18 20:30:23 cvknode25 kernel: [ 100.991309] qla2xxx [0000:00:00.0]-0005: : QLogic Fibre Channel HBA Driver: 10.00.00.02-k-debug.
