Junxiao Bi 3cdf2975d9 qlcnic: fix deadlock bug ... [ Upstream commit 233ac38916 ] The following soft lockup was caught. This is a deadlock caused by recusive locking. Process kworker/u40:1:28016 was holding spin lock "mbx->queue_lock" in qlcnic_83xx_mailbox_worker(), while a softirq came in and ask the same spin lock in qlcnic_83xx_enqueue_mbx_cmd(). This lock should be hold by disable bh.. [161846.962125] NMI watchdog: BUG: soft lockup - CPU#1 stuck for 22s!
