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 ?
