>Description:
        The system paniced with the following messages:

        panic: kernel diagnostic assertion "vp->v_iflag & VI_TEXT" failed:
            file ".../sys/kern/exec_subr.c", line 162

        The backtrace was:

        breakpoint ...
        panic ...
        __kernassert ...
        vmcmd_map_pagedvn ...
        execv1 ...
        sys_execve ...
        syscall ...

>How-To-Repeat:
        I was running pkg_comp to rebuild parts of pkgsrc, and nothing
        else that I would consider remotely demanding.  (Only one build,
        not multiple paralel builds; no backups or "find" jobs running
        at the same time.)

>Fix:
        Unknown.
