SUMMARY: panic messages on E3500 when booting from net

From: Jeff Miller (
Date: Mon Sep 11 2000 - 13:29:20 CDT

Here was the problem:
Solaris 2.6 does not work with the 8MB cache of new processors.

I have new 400MHz/8MBcache cpus. prior to booting from net
(aka jumpstarting), I had to 'limit-ecache-size' from the ok prompt.

ok> limit-ecache-size

I also patched the 2.6 install image on the server by running
"modify_install_server" from the "miniroot?" CD provided with the new
E3500 hardware. This loaded some patches in to the 2.6 jumpstart

I can't do a "boot net - install" on a new E3500.

E3500 configuration:
It has 8 "internal" 18.2Gb FC-AL disks.
I want to load Solaris 2.6. So I used the CD that came with
the E3500 which was for pre-loading a mini root for 2.5.1 and 2.6.
Then, I installed 2.6 5/98 from CD. The default device was c0t4d0.

Then when I want to re-do the install via jumpstart so that postinstall
picks up all of the patches, etc. I run "boot net - install" from the ok

When arp/rarp finds its hostname, domainname, root server
and root directory, it comes back and says:

SunOS Release 5.6 Version Generic_105181-05 [UNIX(R) Systen V Release 4.0]
Copyright (c) 1983-1997, Sun Microsystems, Inc.
panic[cpu14]/thread=0x10404040: recursive rw_enter, lp=10417348 wwwh=10404040
waiters=0 thread=10404040
Clock board TOD does not match TOD on any IO board.

Then it comes back with the Sun graphic and
5-slot Sun Enterprise 3500...etc.

screen goes blank and it comes back with:

Rebooting with command: boot

The `boot net - install` command gets reset to "boot".

Why can't I do: "boot net - install"?

In jumpstart (rules for this particular host), I'm using c0t4d0 as the default
boot device. This is what the pre-Solaris 2.6 install CD said to make it.

What are the "panic" messages about above?

>panic[cpu14]/thread=0x10404040: recursive rw_enter, lp=10417348 wwwh=10404040
>waiters=0 thread=10404040

Thank you,
