I just installed gentoo on my sparc64, and built my own kernel, 2.6.6-rc2. It wouldn't boot with silo-1.4.4 so I tried sparc-sources-2.4.26. Both gave me "Illegal Instruction". I found other people on the forums with the same problem and downgrading to silo 1.3.* works according to them. So I downgraded to silo-1.3.2-r1 and my 2.4-kernel booted. 2.6.6 paniced in a way it didnt with silo-1.4.4 :). Reproducible: Couldn't Reproduce Steps to Reproduce: gentoo 2004.0 comes with silo 1.4.4 1. reboot: Illegal instruction 2. searched forums: emerge silo 1.3.2-r1 3. silo /etc/silo.conf seems to be valid (ofcourse did I do this before too) 4. reboot: works 5. try to reproduce through upgrading again... doesnt give me an error, it just boots...

Couple of questions; What stage did you start with (including stage # and release version)? Did you get the error before or after the SILO prompt? Did you try power cycling the box before downgrading SILO?
I used stage3-sparc64-2004.1.tar.bz2 I got the error after the silo prompt. I got that, pressed enter, it said the kernelversion, and the error. That was it. I didn't powercycle, I just typed 'reboot'.
three Sun Ultra 2s: 2x300Mhz, 1 gig ram 2x300Mhz, 1 gig ram 1x300Mhz, 512 Mb ram new install (disks came as boot-into-solaris-install), started with stage2 of 2004.0. Built binary packages on one box then distributed to the other two. Rebooted many, many times before downgrading, always the same illegal instruction error. 1.3.3 worked on the first try. Other posts on this (including mine): http://forums.gentoo.org/viewtopic.php?t=159221
What's the output of .registers immediately after the error?

Sun Sparc Classic. OBP is the last one made for that model I think. I don't have the number at the moment. I'm going to downgrade to Silo 1.3x tonight.
Today i try to install OpenBSD on my ULTRA2, i dd the miniroot.fs to my swap device, i boot from my swap device, abort install, STOP-A , reboot and silo wont start, i powercycle the ULTRA2, and silo boot again. Using this aproach i can reproduce the bug ALWAYS, so grab openbsd 3.5 miniroot dd into your swap partition and boot from it :) here is the output from .register before a failed boot: {0} ok .registers Normal Alternate MMU Vector 0: 0 0 0 0 1: 0 fffda6c0 d 7f1 2: f0000000 f0000000 800001fff00be08e f0000000 3: fffe0000 0 fefbe000 0 4: 16 0 fefbe000 4000 5: f0023b44 f fffda000 1b0e368 6: fffeff38 4415001600 8000000067f620b6 e 7: fffeefc8 4e 2 f00556a8 %PC f002353c %nPC f0023540 %TBA f0000000 %CCR 44 XCC:nZvc ICC:nZvc After the failed boot: {0} ok boot Boot device: disk:a File and args: SILO Version 1.4.4 boot: Allocated 8 Megs of memory at 0x40000000 for kernel Loaded kernel version 2.4.26 Loading initial ramdisk (943694 bytes at 0x40C00000)...

This thread on the linux-sparc ML seems to relate to this bug: http://marc.theaimsgroup.com/?l=linux-sparc&m=108329396131966&w=2
I was having kernel related booting problems on several Ultra5 systems. kernel versions included 2.4.x and 2.6.x. problems were noticed with Silo 1.4.4/1.4.5 various kernel versions including 2.6.6 2.6.5 2.4.24 2.4.26 OpenBoot versions 3.19 3.25 errors included "kernel illegal instruction" and something like "Fast Data Access MMU Miss" (sorry, I did not record the last error message exactly). Some kernels would boot on some (similar) machines, but not others. I upgraded the OBP to 3.31 (latest for Ultra5/10) and voila. All of the kernels the I have had trouble with are now booting without error. It may be worthwhile to try this if you are able to update your OpenBoot Prom. All of the kernels tested were copied from a system that would not boot without the Install CD. Interestingly, I never had problem with the kernel on the CD-ROM. Hop this helps. TM
Ben tells us that 1.4.8, which I just marked stable, is fixed. Please reopen if not.
