Hi Himanshu, The issue is: When insmod the qla2xxx.ko from 4.15-rc6, linux hang. I have git bisect the commits. The issue was introduced in commit: 726b85487067d7f5b23495bc33c484b8517c4074 qla2xxx: Add framework for async fabric discovery. The previous commit is good: 5d964837c6a743193c63c8912f98834c7457ba5c qla2xxx: Track I-T nexus as single fc_port struct .
