Hi,
Recently I was working with mpslsi3 driver and found that the system just crashed at xpt_action() call. The same driver code is working just fine with other versions of FreeBSD. After digging a little into the CAM layer code I found that: inside scsi_scan_bus()at line number: 1935 first mutex_unlock(mtx) is called and then at line 1974 called mtx_lock(mtx) just before exiting the XPT_SCAN_BUS case. I just swapped the calls and called mutex_lock() first and then called mutex_unlock() and found there is no kernel panic. Driver was loaded just fine but after a while I was unable to operate the system. But pinging to the system was working and the system was up. Is it OK or it looks to be a bug?
