>Description:
This crash occurred during the first run of /etc/daily since the
upgrade to my most recent build of -current, apparently while
/etc/security was doing the pkg vulnerabilities audit or check.
The machine had done some package building (via
pkg_rolling-replace -D MAKE_JOBS=8) on the previous day, as well
as running a couple of emacs processes, xterms, etc.
I've had another VM running a XEN3PAE_DOMU (i386) kernel and
build from the same sources, on the same dom0 host, for 20 days
now, i.e. "running" (but not doing anything but cron jobs), as
it has fewer virtual devices, only two CPUs and one XBD disk, no
packages installed, and no NFS mounts -- it's just a test install.
According to the commit log for the relevant KASSERT() this may
be somehow related to PR port-xen/53506.
Unfortunately it refused to write a crash dump. (Can Xen DOMU
even write core dumps yet?)
Here's the console and ddb output, including the reboot dmesg:
