SUMMARY: netra X1 crashing hard

From: Justin Sheehy <>
Date: Tue Oct 30 2001 - 14:45:08 EST
This is a summary to a problem that I posted in August.  The original
post is at the end of this message.  The reason it took so long to
summarize is that the problem was only manifesting every month or
two.  Thus, I had to wait a while to be reasonably confident that
things were fixed.

I received many responses, most of which were requests for info from
people who were having the same problem.

Several people made helpful suggestions, including:

 - check the power supply
 - check for bad DIMM or CPU
 - install some known patches
 - bring the OBP level up
 - get Sun to deal with the whole thing via warranty

The idea that seems to have done the trick was a suggestion from
Rachel Polanskis.  I installed the following two patches:


I have not had a crash since August.

If you are having problems with X1s crashing hard, I highly recommend
that you install these patches.
