Hi,

Linux 2.6.3-rc2 fails to boot on sparc64. 2.6.2 doesn't boot neither.

The output is :
Allocated 8 Megs of memory at 0x4000000 for kernel

Loaded kernel version 2.6.3    <--- SILO message
Illegal Instruction
{0} ok 

2.6.1 boots without any problem. 
silo v. 1.4.4

We used gcc 3.3 to compile the kernel. Same issue with gcc 3.2.
2.6.1 compiled with exactly the same build environment does boot.

The box is a Sun Entreprise 4000.

Any clues ?
Any other useful information I could provide ?

Hi,

As we reported in [1], Linux 2.6.(2|3) doesnt boot on sparc64. We traced the
problem back to some changes in arch/sparc64/kernel/head.S (2.6.3 does
boot with 2.6.1's head.S).

[1] http://marc.theaimsgroup.com/?l=linux-kernel&m=107643106916202&w=2

output :
Allocated 8 Megs of memory at 0x4000000 for kernel
Loaded kernel version 2.6.3    <--- SILO message
Illegal Instruction
{0} ok 

After a discussion with Ben Collins, it seems that only UltraSparc I are
affected. Could somebody check the new head.S's assembly code ? We are a
bit short here on sparc64 ASM...

Please tell us how we can help.

Thank you,

So backing down to silo < 1.4.0 works with the new head.S on UltraSPARC
I? I don't think the problem itself is in head.S. Changing that would
force silo 1.4.x to not keep the kernel in high memory (would copy it
back down to 0x4000 where the old silo would have put it). I am guessing
the problem is elsewhere.

Try this, keep the new head.S and newer SILO, and edit head.S so that
"HdrS version" is 0x202 instead of 0x300. See if that boots for you
(would confirm my suspicion).

It boots correctly this way. What can we do to help now ?

Can you enable CONFIG_DEBUG_BOOTMEM and boot with "linux -p"?

Here is the output :

boot: linux -p
Allocated 8 Megs of memory at 0x4000000 for kernel

Looping, had to stop it using Break+A.

The same kernel boots without -p.
