My thread is mppLnx_dpc_handler.When it's running at cprintf+0x220 frame,is it
broken out by the intr_thread which is not belongs to mppLnx_dpc_handler?

In mppLnx_dpc_handler , mppLnx_scsi_done is registerd to Qlogic HBA drivers as
callback.I think the intr_thread is restart by Qlogic HBA drivers .

Why the intr_thread stack frames is live in mppLnx_dpc_handler threads stack at
this point.

Thank your!!
