NetBSD 1.1, 1.2, ...?
>Description:
It seems as though setting any watchpoint with ddb somehow
destroys the machine state: I can't get anything but kernel
page faults.
>How-To-Repeat:
control-alt-escape, "watch ipstat", "c"
>Fix:
If this isn't easily fixable, disabling the command would not be
a bad idea.
