Hello everyone,
I'm porting coreboot v4 to a k8-rs780-sb710 based mainboard, and use amd/mahogany and amd/tilapia_fam10 codes as the reference. Now coreboot boots the board and filo loads linux,but the board crashes at a MCE error during booting process. I'm not very know the detail about the MCE, so any suggestions will be appreciated, thanks very much.
The mainboard architecture: CPU: socket F Opteron 2210 EE get_cpu_rev EAX=0x40f13 (1 cpu, dual core) DIMM: DDR2 333M (x1 / x2) HT Link0: off HT Link1: RS780->SB710 HT Link2: off VGA off GFX off PCIE off
coreboot code revision: modified on r5692
The MCE/panic message:
