| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes system hang/crash while firmware dump is attempted with Block MQ enabled in qla2xxx driver. Fix is to remove check in fw dump template entries for existing request and response queues so that full buffer size is calculated during template size calculation. Following stack trace is seen during firmware dump capture process [ 694.390588] qla2xxx [0000:81:00.0]-5003:11: ISP System Error - mbx1=4b1fh mbx2=10h mbx3=2ah mbx7=0h.
