I mentioned in my recent posting about continuous screen scrolling after
upgrading to a 4Mb machine a problem with lpr. This manifests itself
as a 'kernel panic. press reset button' whenever lpr is used. I got a
patch from Frans and I assumed it'd already been posted. Apparently not.
You need to increase the size of the wini stack, I doubled it. The
relevant line is

/usr/src/kernel/table.c    #define WINCH_STACK SMALL_STACK

I changed it to

 #define WINCH_STACK SMALL_STACK*2

and all works well.

Can I take this opportunity to thank all those we replied to the scrolling
problem i.e. Andy, Alan & Jim (Jim, I've tried several times to email you
but our gateways seem to garble the address you gave.. I hope one got
through)

PS: The suggested solution to the scrolling problem was to change 0x7d00
    to 0x7e00 in kernel/stmain.c and kernel/stvdu.c
