[coreboot] Tyan s2912-E reset loop, Please help

[Mark Mc]

Hi, I finally got coreboot compiled correctly and I am getting somewhere as
my console output shows:

Issuing SOFT_RESET...

However it just keeps looping like this, any guidance would be really
appreciated, so far I have tried booting with just 1 dimm (4GB),1 CPU
(opteron 2419) and no PCI-E cards, both stable and master seabios payloads
but so far absolutely no difference.

Cheers
