Illegal instruction with silo 1.4.4 and ultra 1

Illegal instruction with silo 1.4.4 and ultra 1

Hi All,

Recently re-did an Ultra 1 from the ground up.  On the initial reboot, I 
get an illegal instruction with SILO 1.4.4 after it appears to finish 
loading the kernel.  The output (with ctrace) is as below;


Boot device: disk  File and args:
SILO Version 1.4.4
boot:
Allocated 8 Megs of memory at 0x40000000 for kernel
Loaded kernel version 2.4.26
Illegal Instruction
ok ctrace
PC: 40004498
Last leaf: call 10558    from 10400
     0 w  %o0-%o5: (0 fffe8810 1 1 f005b2f8 0 )

I do have the SILO build from which this came still on the drive, so 
first.map and second.map are available for reference.  The version of OBP 
currently on the Ultra 1 is 3.1.1.   This had previously worked before the 
new install so I'm not sure what's the key element here.  I've tried with 
both 2.4.26 and 2.6.6-rc2 kernels to try and eliminate that as a possible 
culprit.

Thanks,

When you say an Ultra 1, do you mean an UltraSPARC 1, or an
UltraSPARC-I?

Also, shoot me the output of ".registers" after the illegal instruction.

It's an Ultra 1 Workstation (143 MHz).

Doesn't look like a silo problem off-hand. This PC is in the start of
the kernel. What compiler are you compiling your kernels with?

Used gcc-3.3.3.  Had to power-off the box for a while today, and when I
turned it back up, it was booting fine.  Both before when it was
having this problem and now if I enabled diag-switch? everything checked
out.  I'll keep an eye on it and see if it does crop up again if I can
better pinpoint conditions.

Thanks for the help,

I was able to reproduce this problem in a scientific way :)
Scenario: Power up and boots cleanly linux. Power up, boot a solaris CD,
halt, and then try to boot linux and it fails. reset-all doesn't help.
Powering off and booting linux again and again works, just when solaris
gets in the way the problem shows up.
Trace:

Check your System.map and see where 0x404498 falls.
