Hi Justin,
Thanks much for the reply, it is my negligence of not have noticed it, and sorry for this.
I inspect the bug report of my tool again and just find that actually lpfc_sli4_intr_handler() also acquires that lock.
lpfc_sli4_intr_handler() -> lpfc_sli4_hba_intr_handler() -> spin_lock_irqsave(&phba->hbalock, iflag);
It seems like this isr is called on an SLI4 type HBA. If consider this one could it be a deadlock problem?
Thanks again, Chengfeng
