I don't think its USB related either.

There seem to be something weird with my setup..
I have
dumpdev="AUTO"
ddb_enable="YES"
in rc.conf.

And a swap partition active. After reboot when its about to save the core I
get error message
/var/crash/vmcore.0 not found

So I can't get any core dump.. Even with debug.kdb.panic=1..

Know what might be the reason?

/var is same as root partition, plenty of free space..
I do get the files
bounds
info.0
textdump.tar.0
in /var/crash/
