breaking/stepping is instantly on my setup. At least so fast that it just
noteable to me.
Regarding the ISP issue are you using avarice or avrdude for programming?
If avrdude, are you then using dragon with ISP or debugwire?
For me programming with avarice is working just fine. But when I use
avrdude (which by itself also works just fine) I have to add some delay
before invoking avarice otherwise avarice cannot open the USB. Because of
that its (unfortunately) impossible to run avrdude as a shell command
through .gdbinit.
