Description: '
Date': 16 May 84 00':17 PST'
Subject': Lisp': No cursor, no caret upon rebooting lisp'
Lisp-System-Date': 11-May-84 08':28':32'
Machine-Type': Dlion'
I got into this state with <lispnew>current>full.sysout (+ some of my own files) while MP shows 1109 (as it should).  When I do a 1 boot to get Tajo I now also hang with an MP code of 915'

Subject': [': Dlion  hung in 915 ]'
I sent a message to Lispsupport last night describing a situation where I get ok MP reading and an ok screen image'
but no cursor when I reboot lisp after a logout (the lisp I used  was '
<lispnew>current>full.sysout.   In this situation I can''t get into'
TELERAID with CTR-SHIFT-DEL either.  The machine doesn''t react to any'
type in and interrupts have no effect.  When I'
try to boot Tajo I hang with an MP code of 915.'
I now recall that this has  happened  to me  3  times in the last 1 1/2'
weeks.  This is why I bring it to your attention.  I have also noticed'
that the Dlion in Levy''s office was hung in 915 for several days'
last week.  I seem to remember that preceding all these incidents I had'
a problem not being able to boot Tajo and ending up with a 915 due to'
my having installed moonboot from <mease>10.0>basics,'
but I don''t have wrong diagnostic microcode on the machine now, at least'
I havent explicitly put it there (I did try a 5 boot, which failed, but'
I wouldn''t expect that to have lasting bad'
On previous occasions I have reformatted my disk when this situation occurred'
(i.e. not being able to boot Tajo), after'
an ill-afted attempt at rebooting lisp after logout.  That'
usually puts me bacck in business, but it didn''t do the trick on Levy''s'
Hope this info helps, or at least that you are'
the right people to send it to.'
Postscript':  Even though my machine did get hung in 915''s inspate of several 1 boots on the eve of the 15th, it booted ok into tajo on the morning of the 17th.  Self-repair? (I noticed that the clearing house wasn''t operating on the evening of the 15th,  could that be relevant?  Kris '
