I am now. Bill, do you know what might be causing this?
It might be a side-effect of Takashi's changes (might, perhaps,
have something to do with spl's?).
To recap, in case anyone missed this, Takashi's kernel that was
modified by him to work on a PB180, works fine, until one tries
to do some serial-port intensive I/O (in my case, dialing up a serial
connection over a modem line and, for example, catting a file,
thus causing much input on the serial line). When I do this, I
get some message having to do with serial timeout's (serial timeout
overflow, or something like that), and then get dumped into the
kernel debugger, from which I must reboot.
Does this sound familiar to anyone?
