I know. Unfortunately I know not much about debugging the kernel. I read
<http://www.freebsd.org/doc/en/books/developers-handbook/kerneldebug-gdb.html>,
but I do not get a kernel core file, because I run the system from a CF
card and use the hds completely for zfs. I have no swap partition I could
dump to.
Is it possible to dump onto a zfs fs? Or is there any other way for
debugging?
