Hello:
For your information I seem to have found a solution
to the problem that I wrote you about last month.
What I did is to re-compile the kernel and choose
for the parallel port chipset driver:
flags=0x61
According to the man page for ppc this disabled the IRQ
by choosing bit 5 to be on (leaving the other bits aside).
I found this by trial and error. The man pages are not
very clear on what all the options are for these drivers.
I still don't understand how the ppbus controller
and drivers work or what all of those options mean. Also,
it seems to me that the man page for lpt is out of date.
If someone could show me how to find out how all this
works I would be willing to have a crack at writing up some
new man pages.

Subject: FreeBSD hangs when running ghostscripe as a print filter.
Hello:
My name is Ed Alley. I am running FreeBSD 3.3 on my home
computer. I have sent you two attachments: my printcap file
and a simplified version of the printer filter that I am running.
Whenever I output a large Postscript file, it appears that
Ghostscript takes all of the CPU ticks; it holds on and won't
release the CPU. While I wait for it to finish, my X-window
pointer freezes and sometimes the system freezes permanently;
I have even had it panic on me with a page fault.
Do you have any idea what is going on? I should note that
the very same setup with Linux runs OK. (:-<)
I am anxious to hear from you on this one; I have
been battling this one for months.
