Hi, Can you see if you can snap some keywords of the backtraces, like usb_xxx usbdx_xxx cam scsi or something like that.
Else I believe there are some sysctl options to prevent the final reboot somehow so that you can write down the messages. --HPS -----Original message----- > From:Thomas Hoffmann <[email protected] <mailto:[email protected]> > > Sent: Thursday 23rd January 2014 17:15 > To: freebsd-current <[email protected] > <mailto:[email protected]> > > Subject: lock order reversals w/ backtrace > > A few days ago I started running 11.0-CURRENT at r260971 for the first time. > > The last couple of times I shutdown my system I noticed 2 or 3 short "lock > order reversal" messages with accompanying backtraces scroll by.
