Hello,
funny questions for me as I'm not a newbie in FreeBSD... ;) But
I'll answer.

The same behavior.

/etc/rc.d/dumpon creates symbolic link /dev/dumpdev. It's present in
my /dev directory. I think a problem is somewhere deeply, probably
with savecore(8). When a panic occurs I see in console process of
dumping (size of RAM, number of pages, dump device etc.) and it's
completely normal.
