Hi Everyone, Well, I've replaced the AMD 2378 CPUs on my SuperMicro H8DME-2 mb with a pair of AMD 2212 CPUs, and I get much much further along in the boot. But it still locks up. The starting and ending messages on the serial console are:
[0x50] <-- 0xf0000000 PCI: 00:06.1 init base = 0xfc140000 codec_mask = 01
It boots!!!!!
I applied the below patch to skip 'codec' initialization (whatever that is) and I was able to boot up to linux.
Can anyone explain what the codec is; perhaps we can turn this 'feature' off permanently? (or make it a .config option).
