Re: kernel panic with latest sources

    I added some additional sanity checks to hopefully avoid a crash
    here, but my guess is that you tried to boot DragonFly with a
    5.x userland, which won't work (5.x binaries are not even close to
    being backwards compatible with 4.x and 5.x's mount would look like
    total garbage to a 4.x kernel).

:I just cvsup'd the latest sources and built/installed a kernel and rebooted.
:Upon rebooted, it was initializing userland when it failed with something
:like this:
:Starting final network daemons: mountd
:Panic: kmem_alloc (134676480) kmem_map too small 8273920 total allocated
:[ hand-transcribed ]
