           Summary: xorg Mouse driver problem causes infinite loop in err
                    log output

the head and tail of Xorg log (was 400MB), pciconf, pkg info

System freeze and Xorg log file files to 400+MB after a possible problem
loading a mouse driver -- running in kvm/qemu virtualization. I have had the
problem at least twice since yesterday when I first intalled FreeBSD 11.  I
have been running FreeBSD 10.1 in the same virtualization environment with no
problems.

The main error might have been this:

[    88.415] (II) Mouse: ps2EnableDataReporting: succeeded
(EE) BUG: triggered 'if (inSignalContext)'
(EE) BUG: log.c:599 in LogVMessageVerb()
(EE) Warning: attempting to log data in a signal unsafe manner while in signal
context.
Please update to check inSignalContext and/or use LogMessageVerbSigSafe() or
ErrorFSigSafe().
The offending log format message is:
Mouse autoprobe: Changing protocol to %s


The last two lines of the output below are repeated in the Xorg log file to
400+MB until I killed it.  The system was unresponsive during that time and CPU
was 100%.  Also note that this command:

vidcontrol -i mode

produces no list of valid graphics devices, whereas FreeBSD 10.1 produces a
giant list when running in a virtual machine created with the same options. 
The original mouse problem might have been related to a possible mouse problem
in the host operating system, but either way, the virtual machine should not
freeze and fill the hard drive.

I installed FreeBSD-11.0-CURRENT-amd64-20150722-r285794-disc1.iso then added
xorg from pkg. Note that when I ran
FreeBSD-11.0-CURRENT-amd64-20150722-r285794-bootonly.iso, xorg would not load
at all (after many attempts).
